Generally speaking, the university should be called the secretariat, and you should be clear about your own work. In fact, all departments of the Student Union can hold special events. The secretariat can hold activities such as the open day of the Student Union, the fellowship of various departments of the Student Union and even the fellowship of colleges and universities (a little upstart), and can also hold practical lectures on office etiquette ~ In fact, the secretariat itself is not a department engaged in activities, but a department that coordinates and connects the preceding with the following, you know ~

Social worker: Do you mean community work department or community health? If there are many activities, such as singing competitions, debates, calligraphy and painting exhibitions, drama clubs, design exhibitions, etc. It goes without saying that community health is actually very easy to do, men and women evaluate each other and there are many calligraphy exhibitions in the dormitory. I hope I can help you.
