Because in ancient China, you had to pass the exam to become a government official. Therefore, the study of the Four Books and Five Classics is also very important. In the Han Dynasty, Emperor Wu of the Han Dynasty followed the minister's advice and established the imperial academy system. Fifty people were selected, and these people passed the exam and were finally promoted to be officials, resulting in the system of selecting officials by doctoral education. Because the place where these people study is called Taishi, it is also called Taishi.
It's just that the disciplines in universities in the past were not as rich as they are now. At that time, the university study system was very strict. At first, the scale of the university was not particularly large, only 50 people. Later, with the development of society, the scale of the university continued to expand. There were 50 to 100 people in the reign of Emperor Zhao of Han Dynasty, only 200 people in the reign of Emperor Xuandi of Han Dynasty, and it had increased to 1000 people in the reign of Emperor Yuan of Han Dynasty. Since then, there has been the establishment of the imperial college system.
However, after the Wei and Jin Dynasties, due to the long-term war, the school was abandoned on a whim. At that time, the scholar-officials, that is, university teachers, were passive in teaching and only wanted to avoid disasters. Imperial academy has long existed in name only, and it was not until Xianning that the University Hall and Guo Zi School were established together that imperial academy gradually developed. Later, Guo Zi School devoted itself to educating children of the royal family, while Imperial College London was a school attended by officials of ordinary society or people who wanted to change their destiny.
