When Lao Wu was getting water at the project department, the paper cup in his hand was knocked over publicly by the project manager. Zhou Qishan, who had cooperated with the company for over ten years, fought for due respect for his fellow workers, only to receive cold management rules. More than thirty veteran masters left Dingsheng with him and re-joined Fangyuan Decoration. Facing personnel changes, project competition, and sudden accidents, Zhou Qishan united people's hearts with clear accounts and clear responsibilities, and also made Du Changhai understand that it was never just a cup of water that drove away the construction team.
