This was taught to the emperor by Zhang during the Wanli period of the Ming Dynasty. In the book "Fifteen Years of Wanli", the historian Huang Renyu analyzed the reasons why a dynasty turned from prosperity to decline with almost dull brushwork. This is because the education of princes in feudal period was too harsh. From the book, we can see that under the pressure of Emperor Zhang and Empress Dowager, the schoolwork burden of childhood is not less than that of primary and secondary school students now, and the requirements for virtue are also based on perfect standards. After Zhang's death, Wanli finally got rid of this high pressure, took the future safety of the country as a tool, vented his personal anger with retaliatory rebellious psychology, and finally dragged the Ming Dynasty to the abyss.
Perhaps the lessons of Emperor Zhang and Emperor Wanli can serve as a lesson for our current education in China. Is the child's psychology and personality distorted under the high-pressure situation? Will they one day retaliate against society and family like Emperor Wanli? If so, what will an ordinary child do to our parents in the future? What will a child with great energy like Wan Li do to society in the future? We dare not imagine, we are not sure, we can only say, in case.
Our education is a gamble, and the pay and the gain are not necessarily in direct proportion. In the future, no one can say for sure.
