The "Night of No Departments" is a very important annual event for us, the bachelor's degree program of Tsinghua College. The main goal is to gather the students of the entire department, foster a sense of belonging, and provide everyone with an opportunity to challenge themselves. The preparation and execution of this event will be done by the participation of all students in the department, including the preparation of performances, venues, equipment, etc. This process of unity and cooperation gives us the opportunity to interact with senior students, work together with classmates, and is also an excellent opportunity to quickly integrate into the department.
