In fact, there are not as many disciples taught by Confucius as you think. More than 100 roommates are his real apprentices, that is, those who have been with him for a long time. You know, there is no such developed educational infrastructure in our country, and lectures are all based on shouting. If there are hundreds of people in a big room, how strong can Confucius speak? So let's just say that his class is not too big, and then some educational ideas he advocates also need to set an example. For example, when he traveled around the world, some disciples followed him and gradually studied with him for a long time, but some may study for several years before going back.
Some educational ideas advocated by him, such as teaching students in accordance with their aptitude, include many types of people among Confucius' disciples. Some people are smart and have bright brains, which means that some people are not so smart, but their personalities are simple, and then their family backgrounds are very different. Some are ordinary civilians, and there is nothing at home except two acres of land. Some are bureaucrats' children, descendants of wealthy businessmen and all kinds of people, but he is not.
During the exam, before the exam, everyone will basically worship Confucius to bless themselves and get a good score. This is a good psychological guidance, not to say that it has any real practical effect, because so many students are selling Confucius. If Confucius blessed everyone, wouldn't everyone have done well in the exam? I'm just saying that I can keep my mind steady and follow such a process, so it's normal for schools, especially universities, to have such a statue of Confucius on campus.
