The lecture hall talks about all kinds of knowledge and experience. Because the lecture hall is an open education platform, it provides students and educators with various courses, including knowledge and experience in various fields such as science, humanities and social sciences. By attending classes, we can broaden our horizons, improve our knowledge reserves, and at the same time communicate with other students to form a broader and more open learning atmosphere. In the lecture hall, we can learn many practical skills and tools, such as how to improve our communication skills, how to manage our time effectively, how to think rationally and so on. These are all important knowledge points that we need to master in practical work and study. Therefore, it can be said that the courses in the lecture hall are very rich and colorful, which is very beneficial to our study and growth.
