The rule of Zhenguan began in the period of Emperor Taizong, especially in the early Tang Dynasty. It was an exchange during the Sui and Tang Dynasties. Due to Yang Di's over-conquest, the national economy was depressed and sparsely populated, and the turmoil in the late Sui Dynasty, in fact, the whole country was in an era of economic depression, sparsely populated, political turmoil and cultural retrogression. Bandits are everywhere, and there are former Sui rebels who refused to accept the Tang Dynasty, so it can be said that the rule of the Tang Dynasty was not peaceful.

2, the main measures of Zhenguan rule

In view of the present situation of the Tang Dynasty, Emperor Taizong inherited his father Li Yuan's thought of taking Tao as the foundation and implemented the policy of recuperation.

In terms of people's livelihood, Emperor Taizong took multiple measures: 1, paying attention to frugality in taxation, implementing the system of land equalization and tenancy adjustment, and paying attention to the mitigation of taxation, so that the corvee did not occupy the time of the people; At the same time, Emperor Taizong advocated frugality, dismissed more than 3,000 maids and ordered the removal of four treasures, which enabled agriculture and people's livelihood to continue to develop. 2, disaster relief and poverty alleviation, the world was in chaos in the late Sui and early Tang Dynasties, the countryside was deserted, and the people were displaced; Emperor Taizong appealed to exile, returned to his hometown, granted land for farming and stabilized people's livelihood. In the early Tang Dynasty, Guanzhong suffered from famine year after year. Emperor Taizong opened a warehouse to help the victims and allowed the people to eat in other states. And took out the imperial palace gold silk, redeemed the children for the victims, and let the victims spend the famine year.

Culturally, we should set up libraries to promote learning, compile classics, revise history, improve the imperial examination system since Sui Dynasty, adopt scientific research to select talents, put an end to cronyism and protect officials.

In anti-corruption, strengthening supervision has made there almost no corrupt officials in Zhenguan Dynasty.

In terms of the rule of law, legislative supervision, setting an example, really realized that the prince broke the law with the common people, and greatly reduced the crime rate during the Zhenguan period.

On the ethnic front, unprecedented opening-up measures have been taken to actively promote ethnic integration and strengthen economic and cultural exchanges among countries.

The imperial court adopted decentralization measures and established a system of three provinces and six ministries, which further divided the rights of prime ministers and balanced the rights of many parties, greatly reducing the possibility of ministers in power in previous dynasties.

3. The purpose of Zhenguan Taizong rule.

In fact, as a feudal monarch, especially a powerful emperor, the purpose of Emperor Taizong's Zhenguan rule was to maintain the feudal rule of the Tang Dynasty.

Opening warehouses for disaster relief, with less money but frugality, is conducive to stabilizing the lives of ordinary people, stimulating farmers' enthusiasm for production and increasing the country's economic strength. In particular, it has a good recovery effect on the damage caused by the chaos in the late Sui Dynasty. The people live and work in peace and contentment, the possibility of national unrest is greatly reduced, and the rule is greatly consolidated.

The selection of imperial examinations broke the situation that gentry monopolized official career since the Three Kingdoms and the Jin Dynasty, and made it a powerful country. Because everyone has to rely on exams to be an official, it is impossible to rely on family selection, so the possibility of officials monopolizing their careers can be eliminated. At the same time, the establishment of the system of three provinces and six ministries divided the power of the prime minister, which was of great benefit to the empire's strengthening of imperial power

Anti-corruption, brainstorming and anti-corruption, in fact, corruption has always been hated by ordinary people, and anti-corruption can greatly win the hearts of the people.

In a country ruled by law, there are uniform standards all over the country, from princes and nobles to ordinary people, even Taizong himself set an example. Everyone knows what can be done and what can't be done. Strict implementation will greatly reduce the crime rate in the country, which is conducive to social stability, and national stability means stability.

Ethnic integration, strengthening exchanges, opening to the outside world, economic development and strengthening foreign trade. As a result of economic development and cultural exchange, more people participate in it, which is conducive to the country's economic development and scientific and technological progress, while reducing the possibility of doing nothing to cause unstable factors and consolidating the rule.
