First of all, China's vocational education started relatively late. Compared with foreign countries, China's vocational and technical education started late. For example, Germany's vocational and technical development is very good, and the industrial society needs a large number of professionals.

Secondly, the social demand for professional and technical personnel has increased. With the strengthening of China's national strength and the development of industry, the demand for technical talents is getting higher and higher, and the demand for high-tech talents is also greatly increased.

In recent years, the practicality of theoretical knowledge has been less and less valued, followed by students from Peking University dropping out of school to study in technical colleges, that is to say, practical ability and practical learning have been more and more valued by the society.
