What are the reasons for the outstanding achievements of calligraphy and painting in Sui and Tang Dynasties? Homework, urgent, short and not too complicated ~ ~

1 Sui and Tang Dynasties were the heyday of feudal society in China. At that time, the society was relatively stable, the economy was prosperous, there were frequent exchanges with other countries, and culture and art were highly developed.

Before Sui Dynasty, landscape appeared as the background of figure painting. In the turbulent Wei, Jin, Southern and Northern Dynasties, the idea of returning to nature prevailed, and many literati retired from the mountains, resulting in a number of pastoral poets and landscape painters.

In the early Tang Dynasty, Emperor Taizong and Li Shimin attached importance to painting as a tool to maintain political power.

The Tang Dynasty was a very developed period of political culture in China. At that time, printing was not popular, and a large number of documents and books were copied, so regular script was extremely prosperous, which was the peak of regular script art in the history of Chinese calligraphy.
