On August 13, CET held day-long team-building exercises in Huairou. The main participants were staff at the supervisor level or higher. These exercises focused on team brainstorming and effort, team cooperation, and how to organize and assign work. The exercises were divided into two parts: morning and afternoon. In addition to interesting events and team training, there were formation drills and physical strength training throughout the day. Such exercises not only provide physical and mental challenges for everyone, but also are a source of inspiration and new ideas for everyone in their subsequent work.
