If it is a multi-class class, it is usually in the lecture hall and other large classrooms, and seats are also available on a first-come-first-served basis. Classes that I don't like now are usually full in the back row and nobody in the front row.

Staircase classrooms are generally common in universities and can also be seen in some primary and secondary schools. This kind of classroom has a large area and accommodates a large number of people. But its biggest feature is that the floor rises step by step, and the farther away from the podium, the higher the seat, so that students with a back seat far from the podium can clearly see the blackboard and the podium without being blocked by students in the front row.

In general, the ladder classroom is not a fixed classroom for individual classes, but a public classroom, so it can be used as a free self-study classroom in free time and can also be used flexibly by activity classes. The amphitheatre has become a landscape of the university campus and a symbol of the liberal academic atmosphere of the university.
