First of all, the state treasury is empty and the government cannot afford compulsory education. In the late Qianlong period, the fiscal deficit and deficit of the Qing government were huge. After the Opium War, there are still huge reparations that are still unknown. Therefore, the funding for compulsory education is impossible.

Secondly, the officialdom is extremely corrupt, and the improvement of compulsory education lacks strong leaders.

Third, the feudal ethical code is deeply rooted, and there is no mass base for changing customs.

Fourth, there is a shortage of teachers. Few people in China have received western-style education, and comprehensive compulsory education is purely theoretical.

Answer the teacher, the above four points are my own thoughts.
