How were the ancient official schools classified?

According to the different educational levels, educational objects and teaching contents of ancient emperors and generals in China, it can be divided into three categories: the highest institutions of higher learning, junior colleges and aristocratic schools. The highest institutions of learning in ancient China were Imperial College and imperial academy, which were the main places for training talents in ancient imperial courts. Imperial academy and imperial academy have accumulated a lot of valuable experience in running schools, prospering academics and developing ancient China culture and science, which occupies an important position in the history of education in China and the world.

Both imperial academy and imperial academy attach importance to exams. Although the forms and methods of examinations are different in different times, the practice of trying to select scholars has broken the system of being worldly-wise, worldly-wise and cronyism, which is still of positive significance to the selection of feudal talents.

For example, in the early Han Dynasty, we created the experience of imperial examination, which was also rare in the history of world education at that time. Later, the ten-day examination, the year-old examination and the graduation examination of the imperial examinations in the Tang Dynasty, the "three-academy examination" in imperial academy in the Song Dynasty and the "integral examination" in imperial academy in the Ming and Qing Dynasties can all be regarded as the inheritance and development of imperial academy's examination method in the Han Dynasty.

Imperial academy and imperial academy emphasized self-study and free academic research. Especially in the Han Dynasty, there were more and more students. In addition to taking the form of large classes, teaching also places special emphasis on self-study to guide students to study and explore academics freely after class. This is a vivid portrayal of imperial academy's free study and academic exploration at that time. Later generations of imperial academy and imperial academy both inherited and carried forward the fine tradition of imperial academy in Han Dynasty to varying degrees, and trained many great scholars.
