How comfortable is a comprehensive TV box？ Comparison and evaluation of three mainstream TV boxes

　　Recently, the system that comes with the old TV at home has some cards, and the cost of changing the TV is relatively high. If you add a TV box, the cost will be much lower. But with so many TV boxes on the market, how should you choose?

　　If the budget is between 300 and 500, among the mainstream products, the three boxes of Aurora 5S, Tmall Magic Box 8Pro and Dangbei H3S are considered to be close in configuration. Since the general target has been selected, I simply start all at once, and tell you which one is more worth buying through comparison and evaluation.

　　In order to save everyone’s time, let’s come to a conclusion this time:

　　Tmall Magic Box 8Pro not only has better hardware parameters, but also performs better than Aurora 5S and Dangbei H in actual measurements. 3 S is even better and is the king of the three TV boxes.

　　

　　In order to facilitate a more intuitive comparison, I have summarized the hardware parameters of the three TV boxes and some measured data.

　　After comparing the parameters in the chart with the actual measurements, you should have a general understanding of the three products. If you want to further understand the detailed process of this comparison, you can continue to read.

　　Performance comparison:

　　Like all smart devices, the quality of the TV box experience depends first and foremost on "performance", and as a user, the most intuitive perception of "performance" is nothing more than four aspects: one is the score score; the other is the boot speed; the third is the APP loading speed; and the fourth is the video startup speed. I also focused on the comparison test of the three TV boxes from these four aspects.

　　[Performance score] Performance score is the most intuitive performance embodiment. The higher the score of a TV box, the stronger its overall performance. Using Antutu score measurement, the score of Tmall Magic Box 8Pro reached 55,812 points, the best score among the three TV boxes, followed by Tencent Aurora 5S, and Dangbei H3S.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S > Dangbei H3S

　　

　　[Boot Speed] In the actual experience, the perception of the performance of a TV box actually starts from the moment you press the "power button". The faster the boot, the shorter the time we need to wait, and the faster we can see the program we want to watch. In the actual boot speed measurement, Tmall Magic Box 8Pro only took 17 seconds to boot, while when Bei H3S took 30 seconds, it was still at the bottom.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S > Dangbei H3S

　　

　　[APP loading speed] APP loading speed is also a side reflection of performance, reflecting the scheduling of TV boxes for "performance". In order to ensure the accuracy of the test, I cleaned the background of each box before the test, and then turned on Kiwi TV, Cloud Audio-Visual Aurora and Mango TV respectively. In the test results, Tmall Magic Box 8Pro still leads in all aspects, even surpassing the second-place Aurora 5S in the loading speed of Kiwi TV and Cloud Audio-Visual Aurora by nearly 1s; while Aurora 5S and Dangbei H3S win or lose each other.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S > Dangbei H3S

　　

　　[Video Startup Speed] The video startup speed reflects the optimization of a TV box for a certain video APP to a certain extent. It is easiest to ignore, but it also tests the TV box manufacturer’s attention to details. Here, Kumeow is used as the test APP to test the opening speed of the same video for three TV boxes. The measured Tmall Magic Box 8Pro took 1.28s, Aurora 5S took 1.72s, and Dangbei H3S took 1.93s.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S > Dangbei H3S

　　

　　[Conclusion] After four rounds of testing, it is not difficult to see that the Tmall Magic Box 8 Pro performs better in all tests, making it the king of performance. Although the price of the Dangbei H3S is similar to that of the other two models, its performance is much worse.

　　

　　So what is the reason for the "performance gap"? In fact, it mainly comes from three aspects: the processor chip, the random access memory and the storage space.

　　The first is the processor chip. It is the core hardware of the TV box’s performance, and its performance not only determines the running speed of the TV box, but also determines the decoding ability of the TV box. Among the three TV boxes, Tmall Magic Box 8Pro uses Amlogic S905x4, and its theoretical performance is the strongest among the three boxes, while the RK3566 used by Dangbei H3S, whether it is 22nm process or 512K cache, is far behind the other two TV boxes.

　　Secondly, random access memory and storage space. The random access memory determines the fluency of the APP during continuous operation, and the storage space, as the hub of data storage and transmission, determines to a certain extent the number of APPs that can be installed on the TV box and the speed of reading and writing content. These two also have an important impact on the performance and user experience of the TV box, so generally when purchasing smart devices, the same price, we should tend to choose these two configurations larger. Among the three TV boxes, Aurora 5S and Tmall Magic Box 8Pro both give 4GB random access memory + 64GB storage space configuration, while Dangbei H3S is only 3GB + 32GB, which is also an important reason why Dangbei H3S is lagging behind as a whole.

　　Audio-visual performance comparison

　　As a TV box, its "audio and video performance" is more a test of the decoding ability of the processor chip and the support for audio standards.

　　In terms of decoding capabilities, in the past, due to outdated technology, some old TV boxes could only support 1080P video decoding at most, so we had no way to output some 4K film sources through it. The three TV boxes tested this time were able to support 8K video decoding, which is completely sufficient for the mainstream 4K and even 8K source videos currently on the market.

　　In terms of clarity, this time using an external U disk to play the local 4K 60fps Blu-ray original video to test, by comparing the three TV boxes to play the same frame of the same film source, it can be seen that the three TV boxes all support HDR 10 + Under the premise, the difference in image quality is actually not big.

　　In addition to the image quality experience, the sound experience is equally important. Among the three TV boxes, Aurora 5S and Tmall Magic Box 8Pro have comprehensive support for audio standards. At present, Dolby Audio and DTS audio in mainstream movies can be output perfectly. When Bei H3S lacks support for these, when playing some movies using DTS audio, there will be only pictures and no sound, which will greatly affect the use experience.

　　[Conclusion] In the audio-visual comparison, Tmall Magic Box 8Pro = Aurora 5S > Dangbei H3S, if you like to watch some original movies or videos, then Tmall mill box The 8Pro and Aurora 5S would be better options.

　　

　　Other comparisons

　　In addition to performance and sound and picture, these three TV boxes also have some differentiated experiences in other aspects. As part of the overall experience, I have included them here to illustrate.

　　[Network Support] A major application scenario of the TV box is to play videos on major video APPs or other networks. In addition to performance, it also has a strong dependence on the network. In terms of wireless network, Tmall Magic Box 8Pro adopts an omnidirectional three-antenna module design, which is better than the other two network signal stability In addition, Tmall Magic Box 8Pro and Aurora 5S provide an RJ45 standard gigabit wired network port more than Dangbei H3S, which is more stable than wireless network transmission. We use TV boxes every day. If possible, it is recommended that you choose a wired network for networking as much as possible, so that it is more stable when watching online videos or using a home NAS to watch local videos.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S > Dangbei H3S

　　

　　[Remote Control] In addition to supporting Bluetooth connection, The remote control of Tmall Magic Box 8Pro also supports the "infrared learning" function, which can learn the infrared signal of the TV remote control, so that only the remote control of Tmall Magic Box 8Pro can realize the functions of turning on and off the TV and the TV box respectively, adjusting the volume, etc., which well solves the trouble of controlling the TV and the TV box to switch back and forth using two remote controls. This is also more user-friendly than the other two TV boxes.

　　[Summary] Tmall Magic Box 8Pro > Tencent Aurora 5S = Dangbei H3S

　　

　　[Interface] In terms of interfaces, although all three TV boxes come standard with HDMI interfaces, Tmall Magic Box 8Pro and Dangbei H3S support HDMI 2.1 protocol, which is faster and more comprehensive in terms of transmission rate, resolution, and HDR and audio support than the HDMI 2.0 protocol supported by Aurora 5S.

　　Although the USB ports on the three TV boxes "seem" to be 3.0 standard, in fact, only Tmall Magic Box 8Pro and Dangbei H3S are USB 3.0 standard, and the blue USB port of Aurora 5S is only USB 2.0 standard, which is reflected in daily use. If external storage is connected, then obviously the data transfer rate of Tmall Magic Box 8Pro and Dangbei H3S is much faster, and the video and file opening speed is also faster.

　　[Summary] Dangbei H3S > Tmall Magic Box 8Pro > Tencent Aurora 5S

　　


　　[Appearance design] In terms of design, Tmall Magic Box 8Pro is the smallest of the three TV boxes, and it borrows the design style of vinyl record player, which looks very delicate. In contrast, Tencent Aurora 5S and Dangbei H3S are not only larger in size, but also relatively simple in design.

　　experience summary

　　In these three TV boxes, Tmall Magic Box 8Pro is better in terms of hardware configuration and real-world experience, and the price is lower than the other two. If you want to buy a TV box at this price, Tmall Magic Box 8Pro is undoubtedly a better choice.

Xingyue L is equipped with Volvo engine, Changan and Haval announce brand-new SUV, and BBA recalls it.

It is expected to pre-sell Haval in April and release the official map of the new model Haval Red Rabbit.

A few days ago, Great Wall Motor officially released the official map of its brand-new model Haval Red Rabbit. It is planned that the new car will be officially opened for pre-sale in April this year. The appearance of Haval Red Rabbit adopts the brand-new aesthetic design concept of "Tide Awakening" of the Great Wall. The front grille is an iconic large-size hexagon, and the interior adopts a straight waterfall design with chrome-plated decoration. The headlights are irregular in shape, and the daytime running lights and headlights are separated. The D-pillar design of Haval Red Rabbit is more rounded, and a large suspended tail is added, giving people a visual effect of sharp style and movement. It is reported that the design of the new car is inspired by the charge posture maintained by athletes when they start to exert their strength.

The new car is positioned in a compact SUV, with a length of 4450mm and a wheelbase of 2700mm in body size, which is quite satisfactory in its class. This car is based on the global intelligent vehicle platform Lemon Platform, and it is the fourth model mass-produced by this platform. Lemon platform has the characteristics of high flexibility, high performance, high safety and light weight, which can give new cars good advantages in intelligence, performance, safety and space ratio.

At present, the power scheme of the new car has not been announced yet, but we predict that the new car will adopt a combination of 1.5T engine with high and low power and 7DCT wet dual-clutch gearbox. Among them, the high-power version can output the maximum power of 135Kw and the peak torque of 270Nm.

Recently, Geely Automobile announced the latest news of Xingyue L. The new car will come standard with Volvo Drive-E 2.0TD power. The maximum power of the 2.0T engine is 175kW (about 238 HP) and the peak torque is 350 Nm. It is worth mentioning that the Star Yue L is a brand-new SUV based on the CMA super matrix. Compared with the Star Yue on sale, the "L" of the Star Yue L has the meanings of Larger, luxurious and subversive.

In terms of design, the straight waterfall net of Xingyue L is very atmospheric, and the "meter-level full screen" of the interior is also amazing, giving people a refreshing feeling. Although the car is positioned as a compact SUV, in terms of body size, it has reached the standards of many medium-sized SUVs, even much larger than the Jetway X70 PLUS, Buick Angkewei, Tiguan L, Chevrolet Explorer and other models positioned as medium-sized SUVs.

Changan Automobile’s new car release frequency is really fierce in recent two years. Not long ago, Changan Automobile officially released a set of new car preview maps, but the car has strict camouflage. It is reported that the new car belongs to CS series. But judging from the lines of the car body, it is likely to be the third car in the UNI series.

The new car adopts a sharp headlight shape, and the body camouflage sticker is printed with all kinds of hot words in the mouth of young people. Obviously, this car user group will also target young people; The lines on the side of the car body are sharp, especially the layering of the two waistlines on the D-pillar is very strong; In terms of power, it is expected that it will most likely be equipped with Changan Blue Whale NE 1.5T L4 engine and 7-speed dual-clutch gearbox. Other aspects have not released more information for the time being, and we will continue to pay attention.

Mercedes-Benz (China) Automobile Sales Co., Ltd. and Beijing Benz Automobile Co., Ltd. filed a recall plan with the State Administration of Market Supervision according to the requirements of the Regulations on the Management of Defective Automobile Product Recall and the Implementation Measures of the Regulations on the Management of Defective Automobile Product Recall. The recall involved some imported and domestic C-class (platform 205) vehicles, totaling 125,568 vehicles. The reason for the recall is that if the vehicle is idling for a long time under the unfavorable heat dissipation environment, the heat generated by the rectifier bridge diode may not be dissipated in time, and individual diodes may also cause short-circuit failure due to exceeding the maximum working temperature, which leads to the temperature rise of the alternator stator coil, which cannot rule out the fire risk and has potential safety hazards.

Therefore, Mercedes-Benz (China) Automobile Sales Co., Ltd. and Beijing Benz Automobile Co., Ltd. will upgrade the engine control unit software for vehicles within the scope of recall through authorized dealers to eliminate potential safety hazards.

Coincidentally, at the time of Mercedes-Benz recall, Audi also announced the recall of domestic A6L, Audi Q3, imported Audi A6 Avant 2.0T and imported Audi A7. The specific production time of vehicles is some domestic A6L 2.0T vehicles produced from April 25th, 2018 to November 24th, 2020, totaling 118,074 vehicles. And some imported A6 Avant 2.0T and A7 2.0T vehicles produced from October 14th, 2019 to November 13th, 2020, totaling 6,724 vehicles.

The reason for the recall is that under certain working conditions when the engine is idling, the imperfect learning function of the camshaft adjuster driving algorithm in the engine control unit may lead to the deviation of the results, which may cause the camshaft not to be adjusted to the correct position, which may lead to the unstable operation of the engine, and in extreme cases, the engine may stop running, posing a safety hazard. FAW-Volkswagen Automobile Co., Ltd. will entrust Audi authorized dealers to upgrade the engine control unit software for vehicles within the recall range free of charge to eliminate potential safety hazards. There are also two Audi Q3′ s recalled because the pulley in the steering gear may have dimensional deviation, which may lead to the incorrect installation of the circlip during the assembly process.

As if it was agreed, BMW Brilliance Automobile Co., Ltd. also filed a recall plan with the State Administration of Market Supervision. A total of 8,114 X3 and iX3 vehicles with production dates from December 29th, 2020 to January 25th, 2021 were recalled.

The reason is that a rocker switch in the automatic seat belt retractor in the middle of the rear row may be positioned incorrectly due to the assembly error of the vehicle in the production process of the supplier. In case of failure, the inductive locking sensor may not work normally in the seat belt retractor, thus causing the passengers to be unable to be fixed on the seat during emergency braking. BMW Brilliance Automobile Co., Ltd. will check the rear middle seat belt for the affected vehicles free of charge and replace the rear middle seat belt if necessary. I have to say that these three brands deliberately chose to announce the recall plan at the same time. It is really a coup to distract consumers’ attention!

Reminder ｜ New scam! Do you know the mobile phone extension？ Someone lost 50 thousand overnight

　　CCTV News:Pretending to be an acquaintance to borrow money, pretending to be a public security bureau, a procuratorate or a court officer to investigate a case, and hiding a Trojan link &hellip in short messages and QR codes; … These tricks must have made everyone immune, but do you know? Some telecommunications services that you have never heard of have also begun to become new traps set by scammers!

The mobile phone was locked and more than 50,000 yuan was stolen.

　　When he woke up, Mr. He in Shenzhen found that his mobile phone was locked. At the same time, a shopping platform account was stolen by strangers. Criminals used white bars to spend and apply for loans, and robbed more than 50,000 yuan overnight.

0

　　Later, Mr. He discovered that his mobile phone had been taken over by a strange number. The short message from the operator shows that this is a business to add a secondary number, and Mr. He’s mobile phone number was added as a secondary number by criminals. When the secondary phone is turned off, all short messages will be received by the primary phone, and criminals will receive Mr. He’s short message verification code during this period, and then commit crimes.

0

"Subnumber" ≠ "kinship number"

　　Without an ID card, a bank card or even a real name, the money is gone. What the hell is a minor number?

　　Many people think of "family number" at first, but "deputy number" and "family number" are not the same thing.

=

　　Family number usually refers to the phone bill package opened by different owners and different numbers in order to make calls between them cheaper, and the secondary number is the "one card with many numbers" service provided by operators. On the basis of not changing mobile phones and SIM cards, users can add up to three real mobile phones as secondary numbers. The main and auxiliary numbers can stand by at the same time, and you can freely choose any number to dial, answer the phone and send and receive short messages as needed.

Don’t reply to text messages too casually.

　　Then, how did Mr. He’s mobile phone number become the "secondary number" of criminals?

　　Reduction of criminal modus operandi

　　Step 1: Buy materials.Criminals buy leaked names, bank card numbers, ID numbers and reserved mobile phone numbers online, commonly known as "four big pieces".

　　Step 2: Fishing.Criminals apply to the users who have mastered the bank card information, initiate the business application of binding the sub-number, and find the target of the crime by casting a net widely. Once you reply by mistake, you are hooked.

　　Step 3: Forced shutdown.Because the main number can only take over the SMS when the secondary number is turned off, criminals usually use two means at this time. One is to use SMS bombing to force the target to turn off the mobile phone, and the other is to use the mobile phone cloud service to remotely operate the mobile phone.

　　Step 4: White Wolf with Empty Gloves.Using the SMS verification code received by the main number, criminals ransacked the online shopping account bound to the mobile phone number.

　　Patterns are stacked, and it is impossible to prevent them! For this kind of fraud, after receiving all kinds of SMS notifications, you must read the content of the SMS clearly and do not reply at will.

"SMS custody" business is also not very secure.

　　After the SMS storage service is opened, you can save your mobile phone messages on the server of the operator. Now, many mobile phone manufacturers’ cloud services are doing the same thing. However, this is a hidden danger function.

　　Case review

　　One morning, Miss Ding saw two short messages from banks and mobile phone operators on her mobile phone, which were sent at 3:43 am and 4:12 am respectively. As soon as the account is checked, the balance of more than 100,000 yuan will be zero overnight! Not only that, Miss Ding also suffered a credit card theft and was "applied" for a bank universal loan of 70,000 yuan.

　　How on earth did all this happen?

　　Reduction of criminal modus operandi

　　Step 1: Hit the database to get all kinds of account information.The so-called "library collision" means using software to try a high probability digital sequence. Using this simple and rude method, the user’s network identity, online banking account number, mobile phone business hall and other accounts can be seen at a glance. Insiders said: "The speed of library collision is very fast, at least thousands per minute. If some good equipment is used, the efficiency is higher and the success rate is above 50%."

　　Step 2: Open SMS storage and SMS interception services to obtain verification code.This is the most critical step. After the opening of this service, the dynamic verification code to ensure the safety of landing has successfully become the bag of criminals.

　　Step 3: Open the physical SIM card.At this point, criminals can pretend to be victims and apply for 4G card replacement service in the online business hall. For the convenience of the people, some operators can express the card directly to the designated address.

　　By intercepting short messages and copying SIM cards, fraudsters can "do whatever they want".

　　As we all know, many important services rely on mobile phone authentication. If you back up the SMS to the server synchronously, it will increase the exposure opportunity. Once the service password of the online business hall is stolen, or the login permission of the cloud service is stolen, it is equivalent to "swimming naked".

The loopholes in the unpopular business are targeted by scammers.

　　The "Research Report on the Trend of Online Fraud in 2016" released by the anti-fraud reporting platform "Hunting Network Platform" proposes that since 2016, online fraud has mainly shown several obvious characteristics:

　　Mobile phone cards have become new theft targets;

　　Jump to the phishing website by using short URL and weiyun sharing link;

　　Well-known recruitment websites and voice platforms for open recruitment;

　　A phishing website that is difficult to distinguish between true and false;

　　The implementation of precision fraud;

　　Fraud professionalism is getting higher and higher;

　　Using loopholes in new business and unpopular business to commit fraud;

　　Use cloud disk and synchronization software to steal information.

　　Among them, the loopholes in mobile phone cards and unpopular business are mentioned.

　　Security experts suggest that we should develop good online habits, don’t click unfamiliar links, don’t fill in our personal information in the website interface with unknown security, and regularly modify the password of social accounts to avoid information such as mobile phone contact information being leaked; Improve safety awareness, develop good habits of using mobile phones, and avoid being infected by mobile phone viruses.

The brand-new BYD Han is officially listed, and the EV version starts at 269,800／DM.

On April 10th, the brand-new BYD Han series was officially launched. The new cars are divided into three series according to the power type, among which there are three models in EV Chuangshi Edition, and the price range after comprehensive subsidy is 269,800 to 288,600 yuan. In addition, there is a limited edition of Qian Shan Cui, which sells for 329,800 yuan. There are 4 DM-i versions, and the price range after comprehensive subsidy is 215,800 to 289,800 yuan; Finally, there is one DM-p version with a price of 319,800 yuan. At this point, BYD’s "Dynasty" series finally achieved DM-i full coverage.

Wechat Picture _20220410151926_ Copy. jpg

At the same time, BYD also announced the listing rights of new cars, including the lifetime warranty of non-operating vehicles (the first owner), the replacement subsidy of 4,000 yuan, free car replacement, free airport parking, free installation of charging piles for the first owner, and 2 years of free car traffic (5GB/ month).

■　EV Edition: A More Powerful New Big Man

Regarding the static introduction of the new Han EV, you can watch the video analysis we made before, and refine the differences between several new versions and the previous generation Han EV in design and modeling.

Han EV double car _ copy. jpg

The first is the fine-tuning of the size. Compared with the previous version, the new BYD Han EV is 15mm longer, while the width, height and wheelbase remain the same. Therefore, although the new Han has become bigger, it is not obvious from the body shape. However, on the other hand, the captain of 4995mm can still enhance the competitiveness of the new Han EV in the same level market.

Size. jpg

PC Meitu 780x440A.jpg

Secondly, the power has become stronger, especially its front motor, the maximum power is 180kW, and the peak torque can reach 350Nm, which is obviously improved compared with the previous generation of Han EV, while the rear electric drive parameters of the dual-motor four-wheel drive version have not changed, and its comprehensive maximum output is 380kW, and the comprehensive peak torque can reach 700Nm.

Han EV power contrast.jpg

The third is the increase of endurance. With the blade battery of 85.4kWh, the new Han EV has a cruising range of 610km and 715km under CLTC comprehensive working conditions, even at the lowest level, it runs farther than the super-long endurance version of the previous generation Han EV.

In addition, it is worth noting that at present, many large and medium-sized pure electric cars with endurance of 700km or more on the market have battery capacities ranging from 90kWh to 100kWh, but the brand-new Han EV can achieve the same effect only by being equipped with 85.4kWh battery pack. It must be said that BYD still has deep technical reserves in the three-power technology.

Comparison of battery capacity and battery life. jpg

In the intelligent part, the new Han EV is mainly upgraded on DiPilot intelligent driver assistance system. The new car will be equipped with 22 sensing components, and at the same time, it will add functions such as highway driving assistance and emergency avoidance assistance, which can better provide accurate and efficient help for drivers.

Han DM-p luxury benchmark. jpg

Wechat Picture _20220410153205_ Copy. jpg

In terms of intelligent cockpit, the new Han EV will be equipped with DiLink 4.0 intelligent network connection system as standard, as well as high-end configurations and functions such as 5G quick connection, dual-frequency positioning, four-tone voice interaction, HiFi-level customized Tanner audio, W-HUD head-up display, DMS fatigue driving warning system, etc., and at the same time support remote upgrade of OTA of the whole vehicle.

Creation edition looks up. jpg

In the new Han EV series, there is also a limited edition of Qian Shan Cui, which not only has an exclusive green color scheme, but also has exclusive configurations and interior and exterior decoration kits such as high-grade suede seats, sports interior kits, UWB digital keys and high-performance stone green four-piston pliers. In terms of power, the power system of this model is the same as the "610KM four-wheel drive exclusive type" of the conventional Genesis version.

■　How to choose the new Han EV?

Among the four models, which version of the new Han EV has the highest cost performance? First of all, from the power point of view, the new Han EV can be regarded as two single-motor front-wheel drive models and two-motor four-wheel drive models, so if consumers need four-wheel drive systems, they can only choose from the "610KM four-wheel drive exclusive model" of 288,600 yuan, and if there are higher requirements for battery life, I think the "715KM distinguished model" is completely sufficient.

Han EV power parameters. jpg

Because as the basic model of the new Han EV, its configuration itself is rich enough, and it can meet most of the daily needs in terms of quality and experience, and even a little surprise.

Comparison of some configurations of Chinese EV. jpgComparison of Chinese EV partial configurations (2). jpg

Of course, the entry level is not the most comprehensive in terms of intelligent driving assistance. If there are high requirements for this part of the configuration, I suggest choosing the "715KM flagship type" because there is not much difference between it and the "four-wheel drive exclusive type" in terms of driving assistance configuration, and the price is only 17,700 yuan more expensive than the entry level, which is still relatively cost-effective.

■　DM-i/p Edition: The Strongest "Chinese"

For the static introduction of the new Han DM-i, you can click on the video to analyze and watch it. As for the DM-p version, there is no obvious difference between it and the new Chinese DM-i version in appearance and interior design, but it has improved its power performance, and it is also the most powerful version of the new Chinese system.

Figure 3 _ Copy. jpg

The power system of the new Han DM-i/p version consists of Xiaoyun-Plug-in special turbocharged 1.5Ti high-efficiency engine and driving motor, in which the maximum power of the engine is 102kW and the peak torque is 231Nm；. In the driving motor part, the DM-i version will be equipped with a front single motor and two parameter versions, while the DM-p version will be equipped with front and rear double motors.

Chinese DM power contrast. jpg

If we simply superimpose the parameters of the DM-p version of the drive motor, it is concluded that its comprehensive maximum power is 360kW and its peak torque is 675Nm, which is very close to the performance of the previous generation of the most powerful EV. In addition, with an efficient engine, the performance can be imagined. No wonder the acceleration of 100 kilometers is only 3.7s s.

Figure 2 _ Copy. jpg

In addition, in terms of endurance and fuel consumption, the new Han DM-i version has a fuel consumption of 4.2L to 4.5L per 100 kilometers under NEDC working conditions, and the comprehensive cruising range can reach 1300km, and the longest pure battery life can reach 242km；; The DM-p version has a pure battery life of 206km and a fuel consumption of 5.2L per 100 km under NEDC conditions.

Interestingly, although the new Han DM-i/p is equipped with a relatively complicated plug-in system, especially an engine, in terms of size, these two models are 5mm shorter than the previous generation Han EV, but other parameters have not changed, and the wheelbase is also 2920 mm.

Figure 4 _ Copy. jpg

In terms of configuration, the new Chinese DM-i/p version is the same as the EV version, which is equipped with a more intelligent DiPilot intelligent driver assistance system and rich intelligent, comfortable and convenient configurations and functions.

Figure 5 _ Copy. jpg

■　How to choose the new Chinese DM-i/p?

In terms of purchase, we see that all the new Han DM-i versions are precursors, while DM-p is a four-wheel drive, so there is only one option for the four-wheel drive power system. In the DM-i version, the "242KM flagship" with a price of 289,800 yuan is the most powerful and has the longest pure electric endurance. If you pursue the ability to travel, it is recommended to choose this one.

Han DM power.jpg

If we consider the configuration, first of all, in the intelligent driving assistance part, we can see that the "242KM flagship" and DM-p version have the most complete number of sensors and auxiliary functions, so if the configuration requirements for this part are higher, the "242KM flagship" is more cost-effective.

Comparison of Chinese DM auxiliary configuration. jpg

However, in terms of safety, comfort and convenience, the functions of the new Han DM-i series are already very comprehensive. If you want a higher-level configuration, I suggest starting with the "121KM distinguished model" with a price of 225,800 yuan, because there are many identical configurations on the "flagship model" on it, but the price difference is at least 64,000 yuan.

■　Bangpingdian

On the whole, the timing for BYD to launch a brand-new Han series is very good. On the one hand, because many heavy products of the same type have been delivered or listed recently, this market segment has become one of the focuses of attention inside and outside the industry. At this time, listing is easy to get better communication effect; On the other hand, it is the time when the brand announced the sales volume and delivery volume at the beginning of the month. BYD’s production and sales data in March performed well, showing excellent brand health, and at the same time boosting the confidence of many consumers who intend to buy BYD models. I believe it can also help the brand-new Han series to get more orders.

As for the specific model competitiveness, I think that Han EV, as the first "veteran" to enter the medium and large-sized pure electric car market, has kept up with the pace of market evolution in time after this update, and has renewed its vitality and maintained its strong competitiveness.

The brand-new Han DM-i/p series actually has no specific competitors in a strict sense. The medium and large plug-in hybrid cars on the same track with it are basically BBA brands of more than 500,000, such as BMW 5 Series plug-in hybrid and Volvo S90 RECHARGE. Therefore, the new Han DM-i/p series will gain more market opportunities and the sales volume can be expected.

＂Transformers 7＂ exposure forecast 6.9 Autobots all attack on the big screen.


1905 movie network news　A few days ago, the film released the "All Army Attack" notice, rap ally GAI called, all the autobots were in place, and the Big Mac camp ushered in the big screen debut!It is not difficult to see from the preview that "Transformers: The Rise of the Super Warriors" will bring an unprecedented experience to the audience.



The strongest villain in the Transformers series, the Universe Emperor, parachuted into the air. He sent a fear beast headed by natural disasters to the earth to launch a siege against the Autobots. At the desperate moment, the long-dormant Big Mac appeared, and Optimus Prime Optimus Primal combined with the big screen for the first time. When they combined, they shouted "Autobots, Big Macs, Deformation and Departure!" The slogan, the atmosphere instantly burns to the extreme. In the ultimate war, Autobots, Big Macs, and human beings join hands to meet the fear beast and the giant scorpion army. The explosion of the deformation confrontation and the grandeur of the action scene will surely detonate the big screen!



"Transformers: The Rise of the Warriors" will feature many Transformers characters, four times as many as the movie, and their shapes, sizes and personalities are different. The producer said: "We have introduced many brand-new decent and villain characters into the movie, which is like a feast for fans, full of Transformers that have never been seen in previous movies." In the Autobots camp, apart from Optimus Prime and Bumblebee, which are familiar to the audience, the new role phantom is very bright, the exclusive avatar skills are dazzling, and the cheerful and talkative personality is also very popular. As many people’s childhood memories, Big Mac landed on the big screen for the first time, and it was full of feelings to see Optimus Primal leading Airazor, Huang Bao Warriors and rhinoceros Warriors to the front. The villain’s natural disasters, nightingales and traps are amazing, and they are evenly matched with Autobots and Big Macs, which will present the audience with a long-lost big screen shocking spectacle!


The dazzling and high-burning action scenes of the film also conquered the media at the premiere, and received rave reviews. Baidu video said: "The special effects are very realistic, the visual effects are good, and the fighting scenes inside are also exciting." The 1905 film network praised: "The combination and confrontation between human beings and the three camps of Autobots, Big Mac and Fear Beast not only upgraded the visual effect and expanded the action scene, but also properly expressed the core theme that in the face of evil and disaster, no matter which race, only concerted efforts can resist everything." The new characters appearing in the film are also widely loved. WANDA CINEMAS thinks: "Two new camps, the Big Mac and the Fear Beast, are introduced. The collision between animals and machinery makes people rediscover the blood that first saw the deformation scene." Sohu Entertainment can’t hide its love for Phantom: "The role of Phantom is a surprise, a chatterbox, and a social cow. Compared with other calm autobots, it is more naughty and friendly, and it is connected with the local atmosphere."


Transformers: The Rise of the Super Warrior is directed by, starring, and Peter Claver Cullen, Ron Pullman, Peter Dinraki, and others are involved in the dubbing. It has been scheduled for June 9, so stay tuned.


Meta is hard and OpenAI, and the domestic ＂small model＂ official announces open source. Where is the ＂Hundred Models War＂ going？

　　Since the beginning of this year, the global Internet giants have set off a "hundred-model war", and Microsoft, Google, Baidu and Ali have come to the end one after another. After more than half a year of competition, technology giants are welcoming a new round of road disputes around the big model ecology: facing the parameter "ceiling", will the future of the big model be closed or open?

　　The open source model can run on a home computer.

　　On August 3rd, two open source models, Qwen-7B and Qwen-7B-Chat, were put on the domestic AI developer community "ModelScope", which were Alibaba Cloud Tongyi Qianwen’s 7 billion parameter general model and dialogue model respectively. Both models were open source, free and commercially available.

　　According to reports, Tongyi Qianwen Qwen-7B is a pedestal model that supports many languages such as Chinese and English, and it is trained on more than 2 trillion token (text unit) data sets, while Qwen-7B-Chat is a Chinese-English dialogue model based on the pedestal model, which has reached the cognitive level of human beings.In short, the former is like a "foundation" and the latter is a "house" on the foundation.

　　The actual test shows that the comprehensive performance of Qwen-7B model is good. Among them, on the English proficiency evaluation benchmark MMLU, the score is generally higher than that of the mainstream models with the same parameter scale, even surpassing some models with 12 billion and 13 billion parameter scales. On the Chinese evaluation C-Eval verification set, the model also achieved the highest score of the same scale. Qwen-7B model is also among the best in evaluating GSM8K in mathematical problem solving ability and HumanEval in code ability.

　　That is to say,In the tests of Chinese and English writing, solving mathematical problems and writing codes, Qwen-7B model is properly a "master of learning", and its score even exceeds the international mainstream model with the same parameter level.

　　Besides, the industry is more concerned about the usability of Qwen-7B model. As we all know, the training and operation of mainstream large models need special AI training chips (such as NVIDIA A100), which are not only expensive, but also as high as 10,000 — per NVIDIA A100; 15,000 dollars, and it is monopolized by countries such as Europe and the United States, and it is almost impossible to buy it in China.The domestic Qwen-7B model supports the deployment of consumer graphics cards, which is equivalent to a high-performance home computer to run the model.

　　Thanks to free commercialization and low threshold, the Qwen-7B model has been put on the shelves, which has attracted the attention of AI developers.In just one day, on the code hosting platform GitHub, the Qwen-7B model has been collected by more than a thousand developers, and most of the questioners are Chinese developers.As Alibaba Cloud said in the statement: "Compared with the lively AI open source ecology in the English-speaking world, the Chinese community lacks an excellent pedestal model. The addition of Tongyi Qianwen is expected to provide more choices for the open source community and promote the open source ecological construction of AI in China. "

　　Open source or closed?

　　In fact, Qwen-7B model is not the first big open source model. In fact, GPT-2, the predecessor of ChatGPT, is also completely open source. Its code and framework can be used for free on the Internet, and related papers can be consulted. However, after ChatGPT spread all over the world, OpenAI chose closed-source development, and the model codes such as GPT-3 and GPT-4 have become the trade secrets of OpenAI.

　　The so-called open source is open source code.For example, once the big model is declared open source, anyone can publicly obtain the model source code, modify it or even redevelop it within the scope of copyright restrictions. To make a simple analogy,The source code is like the manuscript of a painting, and everyone can fill in the colors according to the manuscript to create their own artistic paintings.

　　Closed source is just the opposite of open source.Only the source code owner (usually the software developer) has the power to modify the code, others can’t get the "manuscript" and can only buy the finished product from the software developer.

　　The advantages and disadvantages of open source and closed source are very obvious. After open source, the big model will undoubtedly attract more developers, and the application of the big model will be more abundant, but the corresponding supervision and commercialization will become a difficult problem, which is prone to the embarrassing situation of "making wedding clothes for others".After all, open source considers ecological co-prosperity, and it is difficult to figure out the economic account of how much money can be earned at this stage, and these problems happen to be opportunities to close the source.

　　Open source or closed source, this is a big model of life and death, the international giants have given the answer.

　　Meta, the parent company of Facebook, released the big model Llama2 last month, which is open source and free for developers and business partners, while OpenAI firmly chose GPT-4 closed source development, which not only can maintain OpenAI’s leading position in the generative AI industry, but also can earn more revenue. According to the authoritative magazine Fast Company,OpenAI’s revenue in 2023 will reach 200 million US dollars, including providing API data interface services and subscription service fees for chat bots.

　　Domestic big models have gradually begun to "go their separate ways".Alibaba Cloud’s General Meaning ModelAs early as April this year, it was announced to be open to enterprises, and the open source of Qwen-7B model will go further.ERNIE Bot of BaiduIt has also recently announced that it will gradually open the plug-in ecosystem to third-party developers to help developers build their own applications based on the Wenxin model.

　　In contrast, Huawei does not take the usual path. When the Pangu Big Model 3.0 was released, Huawei Cloud publicly stated that,Pangu modelThe full stack technology is independently innovated by Huawei, and no open source technology is adopted. At the same time, Pangu Big Model will gather numerous industry big data (involving industry secrets, etc.), so Pangu Big Model will not be open source in the future.

　　The big parameters are still small and beautiful.

　　In addition, the open source of Qwen-7B model brings another thought:How many parameters do we need a big model?

　　There is no denying that,The parameter scale of the large model is constantly expanding.Take the GPT model under OpenAI as an example. GPT-1 only contains 117 million parameters, and the parameters of GPT-3 have reached 175 billion, which has increased by more than 1000 times in a few years, while the parameters of GPT-4 have exceeded the trillion level.

　　The same is true of large domestic models. Baidu Wenxin model has 260 billion parameters, Tencent mixed-element model has reached 100 billion parameters, Huawei Pangu model has been estimated to be close to GPT-3.5, and ali tong Yida model has officially announced 10 trillion parameters … …According to incomplete statistics, there are at least 79 large-scale models with over 1 billion parameters in China.

　　Unfortunately, the larger the parameter, the stronger the capability of the large model. At the World Artificial Intelligence Conference, Wu Yunsheng, vice president of Tencent Cloud, has a very appropriate metaphor: "Just like athletes practicing physical strength, weightlifters need to lift 200 kilograms of barbells, and swimmers need to lift 100 kilograms. Different types of athletes don’t need everyone to practice 200 kilograms of barbells."

　　As we all know,The higher the parameters of the large model, the more resources and costs are consumed.However, it is not necessary to blindly pursue "large scale" or "high parameters" to deepen the vertical large-scale model of the industry, but to formulate relevant model parameters according to customer needs. For example, the BioGPT-Large model has only 1.5 billion parameters, but its accuracy in biomedical professional tests is better than that of the general model with 100 billion parameters.

　　Sam Altman, co-founder of OpenAI, also publicly stated that OpenAI is approaching the limit of LLM (Large Language Model) scale. The larger the scale, the better the model is, and the parameter scale is no longer an important indicator to measure the quality of the model.

　　Wu Di, the head of intelligent algorithm in Volcano Engine, has a similar view. In the long run, reducing costs will become an important factor in the application of large models. "A well-tuned small and medium-sized model may perform as well as a general large model in a specific job, and the cost may be only one tenth of the original."

　　At present, almost all domestic science and technology manufacturers have got tickets for big models, but the real road choice has just begun.

The spy war is never over, the spy is around, and the Chinese version of ＂Mr. and Mrs. Smith＂ is so good at acting.

After "Undercover" and "Mask", Zhang Haidong’s third spy war drama "Opponent" came!

There are spoilers in this article.

one

The market in the old city of Xiazhou, the most mixed place, has many pickpockets committing crimes.

No, a pickpocket accidentally put his hand into the policeman’s trouser pocket, and it was too late for him to see the photo of the policeman. Li Tang (Guo Jingfei) chases quickly and ties the thief to a telephone pole.

Then Li Tang wore a police uniform and walked into a dirty rental house. Under Li Tang’s torture, Brother Hei admitted that Yaoji owed three million usurers, but he didn’t know the whereabouts of Yaoji. At the same time, Black Brother also noticed that Li Tang was not a policeman.

In fact, Li Tang is an overseas spy. He usually travels as a taxi driver, and when he finishes his task, he will disguise himself as a variety of roles.

Li Tang’s wife Ding Meixi (Tan Zhuo) is also an overseas spy and a teacher. Ding Meixi repeatedly used her body to lure people into the water in order to obtain information. The two men will do whatever it takes to achieve their goals, and as for the little secret between them, they will only see through it.

On the other hand, Duan Yingjiu (Yan Bingyan), a national security officer, is also looking for the spy Yaoji. By looking up the phone records and comparing the take-away orders, she has locked the most likely hiding place of Yaoji. However, the national security personnel were still late. After seeing Li Tang, Yao Ji committed suicide after saying his last words …

However, the investigation of Yaoji still didn’t stop. Duan Yingjiu began to arrange Ding Xiaohe, a newcomer to Guoan, and his party to collect the information that Yaoji might have left in the bank and analyze who Yaoji left the money to.

Ding Xiaohe is Ding Meixi’s younger brother. Ding Xiaohe announced that he had officially joined Guoan, and the couple were terrified. Ying Jiu had long been suspicious of the couple, which undoubtedly put them in deep danger.

It wasn’t long before Mr. and Mrs. Li Tang received the task of killing Bao Ping, a spy. They switched Bao Ping’s asthma medicine to spray to induce asthma, which led to Bao Ping’s death. The couple will try to explain to Ding Xiaohe why they bought a heart spray that the whole family can’t use. So Li Tang sacrificed his health and directed and performed a heart attack recurrence.

He and Ding Meixi also staged a divorce storm in which the husband found out that his wife had broken a whore, so as to divert the attention of the national security personnel, and a catch me if you can began.

A good script is the foundation, and the actor is the soul of the play. From the realistic "I am Yu Huanshui", the audience will feel Guo Jingfei’s control over the inner complex drama of the little people.

In this play, Guo Jingfei plays a spy who walks on the tip of a knife every day, and I don’t know when he dies. But at the same time, he is also an ordinary person, who will bend his back for five buckets of rice and worry about his daughter’s puppy love. When his wife didn’t come home late at night, Guo Jingfei was lying in bed counting condoms and found that one was missing. She was silent and lost in thought.

The wife found that her daughter always stole her cosmetics and counted condoms for fear that her daughter would have an accident. Clearly missing one, Guo Jingfei paused for a few seconds, eyes flashing, covering up the past. In this performance, Guo Jingfei vividly interprets the forbearance of a spy husband.

The reason why Guo Jingfei can show the fragility and powerlessness of the little people so vividly is that he devoted himself to the script study and really realized the sense of bringing in. The producer of "Opponent" said in an interview: "Guo Jingfei was deeply moved when he got the script. After watching 10 episodes, he couldn’t put it down and decided to participate. " It is not so much that Guo Jingfei is chosen in this play as that they have achieved each other.

Tan Zhuo is also highly compatible with the role of Ding Meixi. Ding Meixi is a glamorous female teacher, an unscrupulous female spy, and a wife and mother. For multiple identities, Tan Zhuo’s performance is very layered.

When she was blocked at home by Duan Ying-jiu, the other party kept asking her for soul torture, and Tan Zhuo ignited the female spy’s inner anxiety, habitually clasping her hands and fidgeting. I’m afraid that a spy with a good psychological quality will panic when encountering this kind of attack.

When her husband broke into the house with a belt to help clear the gap, Tan Zhuoming was relieved. He glanced at Duan Yingjiu timidly, but his heart was exulting. The detailed handling was too skillful.

It was the first time for several actors in the play to cooperate, but they entered the role faster than expected. The producer revealed: "This is due to the trust and tacit understanding they have established when they read the script around."

The content of Opponent is unrepeatable, mainly because the form of spy war is connected with life, involving many bridges that need to be kept secret.

This drama starts from the daily life of spies and national security personnel and reveals their unknown side. For ordinary people, watching a group of mysterious workers fight against each other is a different experience.

"Opponent" doesn’t have the high-tech and enviable work of others. What I feel is that the anti-espionage work is not easy, and the spies are not glamorous on the surface, but extremely dangerous.

The spy couple in the play are faced with the tempering of life. Ding Meixi was found by the school to make up lessons outside, and the bonus was deducted. The original economy was stretched, and she also strayed into the illegal fund-raising trap and lost all her money. Li Tang accidentally broke his tooth in the pursuit mission, and went to the hospital for treatment, but he was scared out by the high medical expenses. The handling of this comedy shows the fact that spies are "smarter than they are" and "being spies is not glamorous".

There is also a positive image of Duan Yingjiu, who sacrificed his life for his mission and responsibility. Not only did family conflicts continue and he could not lead a normal life, but even his body turned red. However, the drama does not use a lot of pen and ink to describe the emotional side, but presents the greatness and selflessness of the national security personnel through life scenes.

Wang Xiaoqiang, the screenwriter of "Opponent", said when he turned on the phone: "I put my views on the world, my emotional experience and my understanding of faith in this story over the years." Because of this, the play is more warm. And a work with temperature can make the audience resonate.

In today’s era of development and peace, anti-espionage work has always existed in various forms that we don’t know. An unconscious word, a casually discarded courier, may reveal secrets. Perhaps "the spy may be around you"-as the drama is broadcast, the context becomes clearer, and the dispute between the national security personnel and the spy becomes more intense. They will continue to compete for victory in the sun. We will wait and see!

＂The Wind Rises in Longxi＂： There is a spy war, and you can see the character’s character.

Taking the little people’s ideal persistence as the eye of the play, and using the type of ancient costume and spy war as the loom, the wind of "Wind Up in Longxi" blew up.

Author: and song

Chen Gong, a spy on three sides, gave his life for the overall situation; Li Yan, who lost power, re-examined the development of Shu; Xun Xu, who knows all the truth, will go to Soochow to set up a new spy network. ……

　

On May 7th, the spy war of the Three Kingdoms in "The Wind Rises in Longxi" came to an end, and the finale explained the fate of all the characters. Also, through the dialogue between Xun Xu and Chen Gong, the "trap" that runs through the whole play was resumed, and Chen Gong was lonely and brave, which made the emotional concentration of the play reach a climax.

Since its launch, the plot and emotional impact of "The Wind Rises in Longxi" have been the key to attract audiences. The drama uses ancient costume and spy war as a kind of nesting machine, taking the fall of the street pavilion as a guide, and dissects the intelligence war between Shu Han and Cao Wei from two little people, Chen Gong and Xun Xu. After life and death, love and hate, they still abide by loyalty, just as director Lu Yang explained to them, "In the face of difficulties, little people can make heroic choices."

　

High-density narration, showing the tension of spy war in ancient costume

Compared with most types of dramas, spy war dramas require more details, drama concentration and story depth. The characters often stir up the times in the dark and reveal the brilliance of human nature in the narrow gap of existence. In order to meet the characteristics of this type of drama, such as spectacle, strong plot and profound conception, many classic spy war dramas on the screen, such as Vow Silent, Hidden, Kite and Pretender, choose to expand the spy sea in troubled times.

　

Accustomed to the silent battlefield in modern history, "The Wind Rises in Longxi" sets the story in the Three Kingdoms, focusing on the secret confrontation of small people under the torrent of the times, which can be said to meet the audience’s innovative expectations for spy war dramas to some extent.

　

In a spy war between Shu Han and Cao Wei, the main characters’ multiple identities kept switching, and there was a struggle between the enemy and me. The ups and downs of characters experience made the story ups and downs and the narrative was extremely compact.

　

The design of long lines and short lines in the play has played a new role in "storytelling". Finding out that Candle dragon, a Cao Wei spy lurking in Shu Han, is a long term, while breaking the bureau after the exposure of Bai Di, obstructing the Qing Ping plan of Cao Wei’s intelligence department and cleaning the secret network of Cao Wei’s intelligence department are short term.

　

The wiring and winding of short stories are not procrastinating, and each line is relatively independent and clear. As a whole, it is complex and wonderful without losing logic. On social media, some netizens described the drama-chasing experience as "the pleasure of rising and falling, and sweeping with the stand".

　

The high-density narrative of "The Wind Rises in Longxi" challenges the double-speed playing habits of current netizens, and makes the audience slow down actively with wonderful foreshadowing. In this reversal spy war, the title of each episode, the dialogue between characters and even some small shots are "hidden mystery". Some viewers have found that some bridges that are difficult to clarify at first can find the answer after two or even three brushes. For example, Chen Gong replaced Cao Wei’s identity as an intelligence agent, but he was able to quickly match the secret code with the roadside driver, laying the groundwork for his reversal as a second-generation "Candle dragon"; After the news of the death of a generation of "Candle dragon" arrived, the camera turned to Feng Ying, the head of the intelligence service. It is self-evident who moved the hand …

Color, light and shadow, props, etc. also assist the story. The turquoise tone of Nanzheng in Shu Han and the grayish yellow tone of Tianshui in Cao Wei help the audience distinguish the regional differences; Men’s beard was an aesthetic and fashion in the Three Kingdoms period, and the beard styles and lengths of different male characters in the play coincided with their personality and status. There are not many props in the indoor scene. Production designer Han Zhong explained, "In the era of frequent wars, people are displaced and the scenery is simple, so the traditional aesthetics of’ sparse and impenetrable’ is chosen to run through the whole drama."

A forbearing and enthusiastic person with insight.

Lu Yang mentioned that he was attracted by the story "The Wind Rises in Longxi" not only because of the combination of spy war and the Three Kingdoms, but also because the little people in this era had no choice but to choose in such a fierce struggle environment.

　

In the play, the protagonists have no legendary appearance, no omniscient perspective and can’t open their "golden fingers". They should maintain a highly rational mental state in extremely complicated situations, "shield" real emotional fluctuations, and even the audience should hold their breath. A scene of where will you go, a husband and wife, is moving. While Chen Gong and his wife Zhai Yue were lurking at the same time, Zhai Yue was tortured to extract a confession after being exposed, and his life was soon over. Their last farewell was all about handing over information, and the sobs belonging to the husband and wife could only be hidden in the darkness.

　

The small emotion of "suddenly venting" in the details, even if it is subtle, also shows the strength of character. In a cold environment, it reveals warm colors. The protagonists are intelligence workers who must be heartless, but also ordinary people who are flesh and blood and have weaknesses that will be fragile.

　

In the thrilling contest and the plot of life and death, the emotional relationship between characters has also been adjusted to a certain extent. The brotherly relationship between Chen Gong and Xun Xu, the in-laws relationship between Feng Ying and Sun Ling, the uncle relationship between Guo Huai and Guo Gang, and the teacher-student friendship between Chen Gong and Li Yan are the emotional ties that connect long and short stories, and they also decode spy war and "intelligence workplace" from the perspective of social relations.

　

People can’t help themselves in troubled times, but it doesn’t mean that little people will be weakened in their ideals and beliefs. Chen Gong, the "chess eye" of the two countries, was never willing to be only a tool man. At the end of the story, he became a "chess player", seeking the optimal solution for everyone while completing his tasks, even if it was at the expense of his own life.

　

Sticking to the morality in one’s heart in one’s own way is an adventure, and it is also an amplification of ordinary people’s "fearless" and "promising". This is also the subtle empathy between the audience and the role.

　

Not only Chen Gong, but Xun Xu, who made a thorough investigation of the "Candle dragon" case, also reflected the stubborn but passionate side of most people.

　

Time goes back to Xun Xu’s involvement in the whole spy war. In the dark interrogation room, he was hanged upside down and drowned. He remembered the ordinary meal he had with his brother Chen Gong and his cousin Zhai Yue. At the dinner table, he (she) who had carried out intelligence work raised their glasses and agreed, "In order to stop fighting" and "For people like you and me to live a good life".

　

Taking this as an appointment, they rushed into the world where candlelight was swaying, but they could learn from sincerity.

　

If the narrative innovation of ancient costume and spy war type nesting makes The Wind Rises in Longxi attract the audience’s attention, then showing the emotional expression of little people who persist in their ideals and maintain their morality in troubled times will retain the audience’s heart to the greatest extent.

Like it, it’s great! China has made a major breakthrough in the field of electric vehicles.

　　Cctv newsThe 2022 Winter Olympic Games will be held in China, and the China government has once again made a promise of "Green Olympics". Around this goal, it is an important link to realize green transportation during the Olympic Games. On August 31st, Beijing Institute of Technology and other research teams released an achievement: the all-weather battery product was successfully developed, that is, the battery of electric vehicles can still work normally under all climatic conditions, including extreme low temperature.

　　In the cold environment, electric vehicles will face challenges.

　　After investigation, during the Beijing Winter Olympics, vehicles will face a low temperature of -20℃ to -30℃, and the use of new energy vehicles will face the following challenges ↓ ↓

　　The charging and discharging characteristics of the power battery become worse!

　　Battery capacity and life will also decay!

　　These will lead to a significant decline in vehicle driving range and vehicle dynamic performance!

　　Sun Fengchun, Director of the National Engineering Laboratory of Electric Vehicles of Beijing Institute of Technology and Chief Expert of the Expert Group of Beijing New Energy Vehicle Association:

　　Now the electric vehicle (cruising range) has reached more than 300 kilometers, but it may only run for dozens of kilometers at MINUS 10℃.The farthest distance between the two venues of Beijing Winter Olympics, that is, the Chongli distance from Wukesong in Beijing to Zhangjiakou is 260 kilometers. How to last the electric vehicle at low temperature is a problem that must be solved.

　　New technology, let electric vehicles break through the low temperature forbidden zone

　　The team led by Professor Sun Fengchun developed the world’s first all-climate battery product by using the rapid thermal conductivity generated by metal heating inside the battery. The key technologies are as follows ↓ ↓

　　A layer of nickel-platinum sheet was added to the existing lithium battery.

　　Connect the power supply, and the battery can be heated quickly!

　　Sun Fengchun:

　　At MINUS 30℃, the temperature of our battery rises to above zero in twenty seconds, so it can work very well and has no influence on the life of the battery. This is the core technology. In other words, there is no forbidden area for electric vehicles, which is a milestone principle and technology in this respect.

　　Low temperature environment, all the key technologies of new energy vehicles are overcome.

　　In addition, key technologies such as vehicle system integration and control in low temperature environment have also made breakthroughs. The cooperative control technology of automatic driving and automatic charging has laid a solid foundation for the application of new energy vehicles during the Winter Olympics.

　　Sun Fengchun:

　　From the battery cell, battery system to the system integration of the whole vehicle, it should be said that the technology has been completely overcome.Our core key components are required according to the standard of low temperature of MINUS 45℃ to ensure that there will be no problems during the Winter Olympics.

　　At the end of this year, all-weather electric vehicles will be launched.

　　According to reports, the first batch of all-weather electric vehicles in the world will be released at the end of December this year, and then they will go to Mohe and other alpine regions for experiments at around MINUS 45 C. It is estimated that in 2020, the development of 11 product prototypes of four types of vehicles will be completed, and the demonstration operation will begin.

　　Zhang Jihong, Deputy Director of Beijing Municipal Science and Technology Commission:

　　We should further integrate some technologies from Beijing, China and even foreign countries to tackle key problems in Industry-University-Research. Whether it is low-temperature battery technology or driverless technology, a complete and comprehensive presentation can be obtained during the 2022 Winter Olympics.

The Table Tennis World Cup will be held in Macau, China in April 2024.

On December 11th, according to Mi Gu Sports, the ITTF announced that the men’s singles World Cup and the women’s singles World Cup will return at the same time, and the competition will be held in April, 2024 at the Galaxy Variety Hall in Macau, China.

Liu Guoliang, Chairman of the Board of Directors of WTT World Table Tennis Federation, First Vice Chairman of ITTF and Chairman of China Table Tennis Association, said: "In April next year, the men’s and women’s singles World Cup will return to Macau, and table tennis fans from all over the world are welcome to gather in Macau again."
