1. The Sui and Tang Dynasties were the heyday of the development of school education in China's feudal society, with a complete range of schools, strict management and a large number of student apprentices, which was unmatched by the previous generation.

2. Therefore, the school education system in Sui and Tang Dynasties, especially in Tang Dynasty, is typical of the school education system in China feudal society.

3. After the unification of Sui Dynasty, in order to consolidate the rule, some measures were taken in education. These measures did not play their due role during the short reign of the Sui Dynasty, but they had an impact on the development of education in the Tang Dynasty. Education in the Tang Dynasty was developed on the basis of education in the Sui Dynasty.

4. The development of school education in Sui and Tang Dynasties is also closely related to the changes of cultural and educational policies in various stages.
