The most important revelation left by Qin's death to future generations is that the implementation of any policy should consider the people's maximum bearing capacity and not at the expense of destroying social productive forces.

The main reason for the demise of the Qin Dynasty was the tyranny of the people. Excessive taxes, corvee military service and harsh criminal law made the people unbearable, and the social productive forces were seriously damaged, which eventually led the people to rise up against Qin.

Extended data:

Qin Shihuang unified the six countries and should have settled the nationals of the six countries. However, he didn't do it. In order to show his supreme power, he promulgated a strict criminal law. Citizens of the six countries are used to living a free and loose life, so they will naturally feel uncomfortable in the face of such severe criminal laws.

Originally, the formulation of the criminal law was not approved by the nationals of the six countries. Now we are also a country ruled by law. At that time, Qin Shihuang wanted to make the country a country ruled by law. But he neglected one thing, that is, everything should be measured, the criminal law is too harsh, and many criminal laws are unreasonable and imperfect. At this time, the resistance will only be greater.

Qin Shihuang successively ordered the construction of the Equator, the Great Wall, Epang Palace and Lishan Mausoleum. In order to build these projects, Qin Shihuang also needed manpower and material resources. Every year, a large number of able-bodied men are requisitioned and people's homes are torn apart. How can such oppression not be resisted?
