For a physical university, it is impossible for it to disappear in real life, because when everyone is studying, after all, there is a learning environment and many educational methods are together. Everyone can listen to the teacher, because the teacher's strength is definitely limited and it is impossible to teach online. Therefore, in every school, it is said that some teachers teach a very large proportion of colleges, and some teachers may have hundreds of students themselves. For this proportion, the existence of physics university is very necessary, because it does not have a good study scope, and everyone can study together in this campus.
