The Southern Dynasties (420 AD - 589 AD) is the collective name for the four dynasties established in the south after the Eastern Jin Dynasty. Since the demise of the Eastern Jin Dynasty in 420 AD, four countries, namely Song, Qi, Liang, and Chen, have appeared in the south, and their existences have been relatively short. The longest among them was only fifty-nine years, and the shortest was only twenty-three years. It was a period of rapid dynasty change in the history of our country. At this time, China was in a period of division between north and south. In the history of our country, the Southern Dynasties and the Northern Qi, Northern Wei, Northern Zhou and other countries in the north were collectively called the "Southern and Northern Dynasties".
