At the age of 19, the young hero started to fight against Sui Dynasty and rode on the battlefield in Zhaoling. "Riding a horse in the past, driving a thousand times today" established the Tang Dynasty with unprecedented national strength in the history of China. At the age of twenty-nine, he took the scepter of the emperor from his father, Tang Gaozu Li Yuan, and began the rule of chastity in the history of China, which made future generations yearn for it infinitely.

Although the Li family belongs to the Han nationality, its ancestral home is Longxi, and it has been ruled by ethnic minorities since the beginning of the fourth century, and it has been 400 years since the establishment of the Tang Dynasty. In 400 years, there are more than enough genes to change a family's thoughts and feelings. Therefore, the Li family has become a highly valued family. They also consider themselves descendants of the ancient philosopher Gigi Lai, so they highly admire the Taoist thoughts of Laozi and Zhuangzi. They also have no bad feelings about Buddhism that flourished since Wei, Jin, Southern and Northern Dynasties. With such an impartial political core and strong national strength, the development of productive forces reached the highest level of a small family society, so people in the Tang Dynasty were full of self-confidence and dared to accept everything with a smile. During the two hundred and ninety years under the rule of the Lee Group, no one was convicted of writing anti-taboo articles. Even if he satirized the emperor and exposed his shortcomings, it was only a piece of cake. Under the feudal system, this is the only dynasty with such a loose and generous political atmosphere.

The prosperity of the Tang Dynasty mainly stems from the relaxed political environment. With a relaxed political atmosphere, intellectuals can make great achievements without scruple. Any country, a nation, a dynasty, even a group, an organization, as long as there is a relaxed political environment and a place for intellectuals, it means the rapid development of material civilization and the harmony of human environment!

I am expanding myself, or adding some concrete examples, such as the story of Wei Zhi's exhortation, or the historian's evaluation of the Tang Dynasty and so on.
