How to evaluate the chastity law advocated by Li Shimin?

I think the evaluation of a historical figure should be carried out from the following aspects: first, from the influence at that time, and second, from the standpoint of the people.

Judging from the influence at that time, the rule of Zhenguan initiated by Li Shimin was mainly manifested in the strong country, clear politics, strong military, prosperous economy and strong national strength, which brought a gratifying situation to the past dynasties. The dynasty initiated by Li Shimin was characterized by incorruptible civil servants, brave military commanders and brave soldiers, who were not afraid of death. The victories of foreign wars again and again made the Tang Dynasty extremely powerful, but different from the past, the war strategy of supporting wars with wars greatly avoided the unnecessary consumption of national strength, did not harm the interests of the people too much, and broke the atmosphere of aristocratic men monopolizing the political situation by appointing people on their merits. Therefore, the influence of chastity advocated by Li Shimin at that time was that everyone was proud of the Tang people and the politics was clear.

Judging from the influence on later generations, the rule of Zhenguan has unprecedented and far-reaching significance, which laid the foundation for the prosperous new century after the Tang Dynasty. Strong military strength and stable political environment made the Tang Dynasty develop very rapidly and laid the foundation for a prosperous future. Some established systems have been used by later generations and played a positive role, such as the three provinces and six departments system and the constant liquidation system.

From the people's point of view, although there have been countless wars, these wars have not frequently harmed the people's interests. Looking at the history of foreign wars in the Tang Dynasty, we can clearly see that many wars are won by less, and many wars are supported by war, which has caused little loss to people's production. Therefore, from the people's point of view, the rule of Zhenguan is undoubtedly a real prosperity compared with history.

Ouyang Xiu in the Northern Song Dynasty: "Sheng zai, the fierceness of Taizong! In addition to the chaos of the Sui Dynasty, it is better than soup and martial arts; The beauty of governance is that a few percent of people are healthy. There have been merits since ancient times, but not since the Han Dynasty. "
