The purpose and theory of China's socialist education is to provide scientific and technological knowledge to develop productive forces and meet the needs of socialist cause. Since education is the main tool to realize the modernization of science and technology, any investment in education is considered to be fruitful because it directly promotes economic development. Facing the demand of industrial and agricultural production, it is very important to train technicians and labor force. This is because there are two kinds of labor systems for workers from rural and urban areas and two kinds of education systems for urban and rural students. China's educational theory is regarded as the integration of the principles of his own educational heritage and Marxism-Leninism.
