First, the Central Plains of China is basically unified.

The second is to completely cut off the root of the separatist regime in the buffer region, adopt a political system of strong cadres and weak branches, strengthen centralization, and check each other among the central departments to prevent consorts, eunuchs and military commanders from usurping power.

Third, respect intellectuals. In the end, intellectuals were basically not killed except for rebellion.

Fourthly, the policy of attaching importance to agriculture and restraining commerce in previous dynasties was abandoned, which greatly stimulated domestic and foreign trade and laid the foundation for China's silver-based currency.

Strengthen centralization: (1) centralization of military power: remove the military power of imperial generals and transfer them to other places to serve as our army. Then weaken the real strength of our army and make it exist in name only. Then, the command of the imperial army was divided into three parts, all of which were directly responsible to the emperor. The Privy Council is established, which has the power to transfer troops, but does not directly command the army. The generals who command the army have no power to dispatch troops, which makes them contain each other.

(2) concentration of administrative power. In the central government, officials, Tang envoys and third secretaries are set up to weaken and divide the power of the prime minister, and the three powers of military, political, civil and financial affairs are separated. At the local level, civil servants were appointed as county chiefs; And set a general judgment to contain each other.

(3) Concentration of financial power and judicial power. Set up transshipment to transport most of the local income to the central government; At the local level, judicial personnel are appointed by the central government, and the death penalty must be reported to the central government for examination and approval.
