Why did BYD's sales of new energy vehicles in December 2021 fall far short of the expected 100,000 units? Was it a sales bottleneck or a production capacity issue? Or was it the impact of the epidemic?

BYD: Hello! In December 2021, the company's new energy vehicle order demand continued to be strong and maintained a sustained growth momentum; affected by the epidemic in Xi'an in the second half of the month, the output of the company's Xi'an automobile production base was affected to a certain extent. As of January 3, 2022, the production of the Xi'an base has basically returned to normal. Thank you for your attention to the company!
