Yu Chengdong ridiculed Xiaomi again: Glass silver plating will affect the mobile phone signal, and the effect is better with heat insulation film
After the recent release of Xiaomi SU7, everyone found that the one who ridiculed Xiaomi the most at the press conference was actually Huawei's Yu Chengdong. Yu Chengdong kept saying "far ahead" at the press conference before, but now Yu Chengdong has been ridiculing Xiaomi at the press conference, which is really a bit unbelievable.
Here's the thing, at the Xiaomi SU7 press conference before, Lei Jun told us that the Xiaomi SU7 front windshield has three layers of silver plating, which can block 99.% of ultraviolet rays and 97.6% of infrared. As we all know, silver is not cheap, and it costs several dollars per gram. So if the front windshield is silver-plated, it will also increase the cost a lot. That's why Lei Jun will use this specifically to promote and tell us that his Xiaomi SU7 materials are absolutely real.
But at the press conference of the new M5, Yu Chengdong also talked about the silver plating of the front windshield.
Yu Chengdong: "Why don't you also silver-plate the front windshield and make silver-plated glass? After the windows of all cars are silver-plated, the same problem is the same as that of the Rolls-Royce Cullinan, the mobile phone signal is very weak in the car, and it has a shielding effect on the electromagnetic field. I was born to study radio, and I know this better. So we send the front windshield heat insulation film, the effect will be better. ”
So this time Yu Chengdong ridiculed Xiaomi SU7 again, saying that it is completely meaningless for Lei Jun to coat the car glass with three layers of silver, and it will also affect the signal of the mobile phone in the car, causing trouble for users when using it. So it's better to be like them, directly send a front windshield heat insulation film, not to mention cheap, the effect is better than this.
It is reported that Yu Chengdong has ridiculed Xiaomi SU7 more than once, and he has also ridiculed Xiaomi about the Xiaomi mobile phone holder before. Even the media reported that Huawei's offline stores are still cutting off Xiaomi's customers. Perhaps for Yu Chengdong, he also believes that Xiaomi is currently Huawei's biggest competitor. But in the face of Yu Chengdong's ridicule, Lei Jun was not angry once. On the contrary, when I treated Zhiji Auto, because the press conference marked the wrong parameters of your car, I sent three Weibo posts to force Zhiji Auto to apologize. The two different treatments have made netizens also discuss.
However, Yu Chengdong graduated from Northwestern Polytechnical University with a bachelor's degree, and he really learned radio. Now, he has been working at Huawei for 31 years. It is reported that Yu Chengdong and Lei Jun are also old friends who have known each other for many years, perhaps this is the reason why Lei Jun has not been angry.
