There were 3,000 students (7,000 words) in the Western Jin Dynasty. According to the regulations of Jin Order, those who pass the exam can visit a doctor. The great change of the education system in the Western Jin Dynasty was the establishment of Guo Zi school for the children of bureaucrats above grade five, which formed a dual-track system of separate education for nobles and lower-class scholars, and coexistence of Guo Zi school and imperial academy.
School education declined in the Eastern Jin Dynasty and revived in the Southern Dynasties. Most of the students in Guo Zi are the children of gentry officials known as "Zhou Guo" or "Zhou Shi". They can enter the official position through the Ming Dynasty, while in imperial academy, there are often only doctors and no students.
During the Sixteen Kingdoms period, some ethnic minority regimes also set up imperial academy, four schools, county Chinese studies and law, with limited student status, generally limited to ministers or their children. But the rise and fall of political power is uncertain, and schools should set their own time. By the time of Emperor Daowu of the Northern Wei Dynasty, a school called Guo Zi imperial academy was established. Don't run a business school again. Guozixue was renamed China Calligraphy, and later it was changed back. The county school is also called imperial academy. During the reign of Emperor Xiaowen and Xuan Wudi, four primary schools were added, forming a system of three schools: Guo Zi School, imperial academy School and four primary schools. From the late Southern and Northern Dynasties to the Sui Dynasty, three schools of thought, namely, learning law, calligraphy and arithmetic, were gradually formed.
