No. Ma Yusheng didn't defect. Ma Yusheng made a speech at the meeting and made some suggestions to Zhao Chuanqi. Zhao Chuanqi accepted it on the surface, but in fact he was unconvinced. Zhao Chuanqi knew that Ma Yusheng was very angry at the meeting behind his back, so he went to the meeting and had an argument with Ma Yu. Ma Wanzhong felt that the battalion commander was struggling, and hoped that Zhao Chuan could grow up as soon as possible.
