Lei Jun posted a message on Weibo to warm up for the Chengdu Station of the Xiaomi China Endurance Championship, which will start tomorrow. He revealed that the Xiaomi SU7 Ultra will serve as a safety car and medical car to escort the event, and will also bring a wonderful drift performance at the opening ceremony. In the comment area, some netizens asked Lei Jun whether he would come to the Chengdu Championship or the Shenzhen Auto Show. Lei Jun responded: "Both events are very interesting, but I really can't attend. Xiaomi YU7 is about to be launched, so I'd better concentrate on the preparations before the product is launched!"
