HKCSS: Hundred Regiments Battle (the landlord probably knows, so I won't go into details)

Student Union: There seem to be many, such as costume culture festival, your stage singer contest and dormitory culture festival. In addition, the students' union is also responsible for some traditional political activities, such as 129 chorus contest (which all colleges attach great importance to), May 4th Culture and Art Festival, with sketches, singers and presenters.

Work-study program: It seems to be a weekend book fair, with many commercial activities.

Art Troupe: At the end of each year, the art troupe will have many large-scale performances with very high quality. There seems to be a performance season in the graduation season. Specially recommend the drama troupe! The National People's Congress Drama Troupe has a history of 20 years, and it watches graduation plays every year. Very wonderful, no less than the troupe in the society. Now the National People's Congress Drama Troupe is basically the best drama troupe in Beijing, and it won an international prize some time ago.

Other large-scale activities are organized by some colleges, such as the wind load of business schools, the wings of social population and so on. Let's forget something we haven't remembered. I hope it helps you.
