China has a large population and per capita educational resources are scarce. In the past, the education level of China people was generally low. However, China's economic capacity is limited, and it is impossible to invest more education funds to develop quality education. In order to let the public learn knowledge quickly, exam-oriented education is implemented. Examination-oriented education has a set of simple and unified standards, which can be popularized and has low cost, especially low labor cost. A large number of low-level teachers could also serve, which was the most important thing in China at that time.

Second, exam-oriented education, as a selection system, is relatively the fairest.

Because it excludes the influence of all congenital conditions except IQ as much as possible. Taking the college entrance examination as an example, scores determine success or failure, and are not affected by external conditions such as family background and subjective evaluation. It can be said that this is quite fair.

Third, it can help ordinary people succeed.

Generally speaking, as long as we work hard, we can get good grades. Then, we have a chance to go to a big city or find a good job. It can be said that exam-oriented education provides ordinary people with opportunities to change their lives. Examination-oriented education is more conducive to the mobility of classes and gives ordinary people a way to quickly improve their social status.
