On March 23, Chinese carmaker BYD (SZ.002594) announced on its official WeChat account that the Yun Nian system will be released soon.

According to the information revealed on the website of the Trademark Office of China, BYD has registered a new trademark called Yun Nian. 

However, BYD didn't clearly explain the purpose of the system in the announcement, but explained the meaning of the two Chinese characters, "Yun" and "Nian". 

Sources were cited as saying that Yun Nian is an independently-developed heavyweight technology that would facilitate the intelligent development of new energy vehicles. Some Internet users speculated that the new technology could be a supercomputing platform, but from the literal sense, Yun Nian should be related to comfort, stability, etc. It might be a new chassis technology, similar to CDC electromagnetic shock absorption. 

In fact, the technologies announced by BYD every year have caused quite a stir, such as the previous "blade battery" and "DM-i Super Hybrid". 

According to BYD's official Weibo account, its Yangwang brand has released the Yisifang technology platform, as well as the first mass-produced car built based on the platform - Yangwang U8, demonstrating the capabilities of the Yisifang technology platform in extreme off-road scenarios for the first time.

As of the market close on March 23, BYD closed at 245.49 yuan per share, up 0.94%, achieving a market value of 714.66 billion yuan.
