In the autumn and September of the first year of Wu Huanglong (222), Sun Quan, Emperor Wu, made Jianye its capital (now Nanjing, Jiangsu, known as Jiankang in the Eastern Jin and Southern Dynasties), and Nanjing became the capital of the feudal dynasty for the first time. Since then, Song, Qi, Liang and Chen of the Eastern Jin and Southern Dynasties have successively established their capitals here. From Dongwu to Chen Dynasty, China was called "Six Dynasties" or "Six Dynasties" in history. During the Six Dynasties, the southern economy and culture developed rapidly and made remarkable achievements.

The Six Dynasties lasted for more than 300 years, and the average life expectancy of each dynasty was about 55 years, with rapid rotation. I don't know how many people covet the throne and depose others themselves. During the Warring States, Qin and Han Dynasties, the hotel in Baoshiyu was called "Chuanshe". Yan Shigu's annotation said: "The family heirloom has stopped, the predecessors have gone, and future generations will come to take a message." Gai Kuanrao, when Xuan Di proclaimed himself emperor in the Han Dynasty, compared the change of wealth to "carrying on the family line" (Biography of Gai Kuanrao in Hanshu). In a world of war, life is like morning dew. Peng belongs to erigeron of Compositae. Its leaves are scattered all over Peng Like, and its branches are bigger than Ben. When the wind blows, it turns. Cao Zhi's Miscellaneous Poems wrote: "Turn the eaves away from the roots and shake with the long wind." This is the complicated era of the Six Dynasties: on the one hand, the ruling class fought for power and profit and plundered each other; On the other hand, intellectuals tend to be wild, talk about metaphysics and truth, and despise etiquette. No matter the aristocrats in the upper class or the working people in the lower class, they always yearn for the pure land in the west, convert to Buddhism, worship fragrant flowers and hope for happiness in the next life.
