What was Buddhism like in its heyday in China?

The Eastern Jin Dynasty, the Southern and Northern Dynasties, the Tang Dynasty and the Northern Song Dynasty were the most popular periods of Buddhism in China. During the Eastern Jin Dynasty, Buddhism spread all over the country. At that time, people in the upper class were proud of believing in Buddhism, and even fought to rob monks. Du Mu has a poem: 480 halls in the southern dynasties, many towers in the misty rain. It is about the prosperity of Buddhism in the Southern Dynasties during the Southern and Northern Dynasties. During the Tang Dynasty, Buddhism flourished because of the emperor's belief. Until the Northern Song Dynasty, Buddhism did not decline, but the northern minorities (Liao, Xixia and Jin) also advocated Buddhism very much.
