Yu Chengdong and Ma Dong started a live broadcast. During the live broadcast, Yu Chengdong introduced and shared the three products Wanjie M9, Xiangjie S9, and Zhijie R7 to Ma Dong. Yu Chengdong said that R7 may lose money when it first starts selling, ranging from 20,000 to 30,000. However, as mass production increases, there may be no loss, and when the volume is larger, there may be a small profit.
