History has always emphasized the prosperity of the Tang Dynasty. How prosperous is it?

The territory of the Tang Dynasty once reached the Aral Sea in the west, Siberia in the north, Sakhalin Island in the east and 18 degrees north latitude in the south. It is one of the most extensive dynasties in the history of China. According to statistics, during the Tang Gaozong period, the land area of the Tang Dynasty reached 125 1. 1.9 million square kilometers, and the land area of China now is 9.6 million square kilometers. According to unofficial history's records, the territory of the Tang Dynasty reached 1.5 million square kilometers in its heyday, but this view is controversial. After that, the area of the Northern Song Dynasty was only 2,835,600 square kilometers, which shows how vast the territory of the Tang Dynasty was.

The Tang Dynasty is famous for its talented people. They are called the five great literary masters: Li Bai, Du Fu, Han Yu, Bai Juyi and Liu Zongyuan. Xuanzong Li Longji founded the "Pear Garden" because of his love of music and dance, which is equivalent to the current Beijing Film Academy or the Central Academy of Drama. The famous Color Feather was created by Xuanzong himself, and it is a bright pearl in the music and dance history of China and the world.

Apart from great achievements in literature and music, as far as fashion trends are concerned, the Tang Dynasty is like France today. The clothes, costumes and hair accessories of the Tang people were widely infiltrated in the Asian cultural circle at that time. Until now, Japan, North Korea, South Korea and other countries still retain some fashions of the people of the Tang Dynasty, and Japanese kimono evolved from the costumes of the Tang Dynasty. The architectural design of the Tang Dynasty is also the object of imitation in various countries. Looking at today's Japan, South Korea, North Korea and other countries, all retain the ancient buildings in the Tang Dynasty style. The cultural infiltration of the Tang Dynasty did not stop there. The tea ceremony in Japan was learned from the Tang Dynasty, and the calligraphy art in Asian countries was also learned from the Tang Dynasty. Even the political ideas of the Tang Dynasty were applied by various countries.

During the prosperous Tang Dynasty, a large number of outstanding politicians emerged, among which Wuji, Fang, Chu Suiliang, Yao Chong, Song Jing, Zhang Jiuling and Di were famous. In addition to the virtuous minister, there must be a virtuous gentleman. Li Shimin, Wu Zetian and Li Longji are all famous emperors, especially Li Shimin. He was meritocratic, good at listening to good words, initiated the rule of chastity, and was one of the emperors with the highest evaluation in the history of China. Li Shimin's Sun Chang Wuji, Wu Zetian's Di Renjie, and Li Longji's Zhang Jiuling jointly pushed the Tang Dynasty to the peak of history, created a great moment of the prosperous era of Kaiyuan, and made it a world superpower.

In the heyday of the Tang Dynasty, that is, in the 7th century A.D., Li Longji, Emperor Xuanzong of the Tang Dynasty, put down the court struggle and ascended the throne, which opened the "Kaiyuan Prosperity" for nearly 30 years. The prosperity standard of ancient society should first be measured by agricultural productivity. During the Kaiyuan period, Datang built a large-scale water conservancy project. According to statistics, 38 water conservancy projects were built in Kaiyuan and 8 in Tianbao, totaling 46 projects. Xuanzong also cultivated land in the whole country, and the development of agricultural production made the grain stored in local government warehouses pile up like mountains. With the improvement of farming technology, rice seedlings are widely transplanted. Tea production was greatly developed in the Kaiyuan period. The world's first tea monograph "Tea Classic" appeared in the Tang Dynasty, and the trend of drinking tea began in Sheng Xing in the Tang Dynasty. Production tools have also been improved, and a new agricultural tool, Qu Yuan Plough, has emerged. Create a new irrigation tool-pipe truck.
