Li Shimin learned the lesson from the demise of the Sui Dynasty and thought that "water can carry a boat, but it can also overturn it". Therefore, he often warned officials to deal with the relationship between rulers and people.
Emperor Taizong also attached great importance to talent selection and talent discovery. Emperor Taizong knew that "the most important thing in politics is to get people" and regarded the selection of outstanding talents as the top priority of the court. He stressed the need to have both ability and political integrity, not to avoid personal relationships and pay attention to morality. In addition, the further improvement and implementation of the imperial examination system in the Tang Dynasty also opened up a basic way for the extensive selection of talents.
Emperor Taizong was able to give Bona advice with an open mind. Wei Zhi is particularly prominent among the lecturers. He once said to Emperor Taizong, "Listen to what people say clearly, but listen to what people say in dark." Kevin·Z and Emperor Taizong discussed this issue. Frankly speaking, although it aroused the anger of Emperor Taizong, they never gave in. In the early Tang Dynasty, Emperor Taizong was good at coachable, which avoided many disadvantages brought by the emperor's arbitrariness under the feudal monarchy.
Second, economically, we should implement the policy of "rest and recuperation", implement light and extravagant taxes, and pay attention to developing agricultural production.
"The country is people-oriented, and the people take food as the sky." In order to reduce the burden on farmers, Li Shimin attaches great importance to agricultural production and actively implements a series of policies that emphasize agriculture and light taxes. At the end of Sui Dynasty and the beginning of Tang Dynasty, wars were frequent and the population was sparse. On the one hand, Li Shimin tried hard to implement the land equalization system and the land rent adjustment law to limit the monopoly and possession of land by clans and strongmen; On the other hand, encouraging farmers to reclaim wasteland has greatly improved their enthusiasm for production. At the same time, Li Shimin paid more attention to thrift. After becoming emperor, he still lived in palaces of the Sui Dynasty, most of which were dilapidated. Luoyang was flooded and people's houses were destroyed. He also ordered some palaces in Luoyang to be demolished and firewood distributed to the people to repair the buildings.
Third, militarily, the military system of "combining soldiers with farmers" is implemented.
In the early Tang Dynasty, the system of officers and men of the previous generation was followed, which was further improved by Emperor Taizong. The system of officers and men is based on the system of equal land. Government soldiers go out in wartime, usually stay in the countryside, farm in spring, summer and autumn, practice martial arts in winter, and the soldiers and farmers are integrated. It has a positive effect on "the rule of Zhenguan". During the reign of Emperor Xuanzong of the Tang Dynasty, due to the serious border crisis and in order to conform to the current situation, the government soldiers were changed to recruit soldiers, raise horses and plow fields. With their strong national strength and strength, they gradually recovered their lost land and safeguarded the unity of the country and the peace of the frontier. Soon, the famous "Kaiyuan Shi Sheng" appeared. It can be seen that the correctness of the military system is also an important symbol and guarantee for a country's prosperity.
Fourthly, in terms of culture, we are determined to study history and advocate Confucianism.
Li Shimin was well aware of the principle of "strengthening the country with military strength and rejuvenating the country with strength", attached importance to reforming the imperial examination system and developing school education, which created favorable conditions for the prosperity of Tang culture.
During the Zhenguan period, respecting Confucius and Confucianism and promoting learning and teaching were one of the key periods for the development of Confucianism. The Kaiyuan period was the most prosperous period of poetry creation in the history of China literature, and great poets with different styles such as Li Bai and Du Fu appeared. The prosperity of poetry creation can not be separated from the advocacy of Xuanzong in Tang Dynasty. Tang Xuanzong loved Li Bai's poems, so he directly promoted Li Bai from an ordinary person to imperial academy. He also called Li Bai into the palace many times and gave him generous treatment in material life. Tang Xuanzong's behavior encouraged more people to devote themselves to poetry creation and pursue perfection, so that the art of poetry was fully developed.
Fifth, in ethnic relations, we should adopt a more equal ethnic policy, such as "integration of Chinese and foreigners", conquer cautiously, attach importance to border security, and replace war with peace.
The relationship between the Han nationality and the border ethnic minorities has always been valued by the rulers of past dynasties. Emperor Taizong handled ethnic contradictions and improved ethnic relations through a more enlightened ethnic policy. For those who have been conquered and voluntarily joined the minority tribes, we should be careful not to forcibly change their lifestyles and customs, and appoint their original leaders to hold official positions at all levels to manage the people in their own regions or tribes. At the same time, give them farm tools, cattle and other items to help them develop agricultural and animal husbandry production. In addition, Emperor Taizong also paid great attention to strengthening ties and unity with ethnic minorities by means of "affinity". He married the imperial daughter to the leaders of ethnic minorities many times, and the most far-reaching influence was that Emperor Taizong married Princess Wencheng to Tubo Songzan Gambu. The emperor's war and the successful use of his hands realized the unity and stability of the frontier and the close exchanges between ethnic groups.
