In 2.3 17, Si Marui, the king of Langya, established the Eastern Jin regime, with Jiankang (now Nanjing) as the capital, which was the first peak in the history of Nanjing's urban development.

4. In 479 AD, he forced Song to meditate, became emperor on his own, established Nanqi and built Jiankang (now Nanjing);

5. In the first year of Tian Jian (502), for the sake of Liang Wudi and Dujiankang (now Nanjing), Xiao Yan abandoned the emperor to stand on his own feet and proclaimed himself emperor;

6. In the first year of Yongding (557), Chen Baxian established the Chen Dynasty and Jiankang (now Nanjing) on behalf of Nanliang.

Wu, Eastern Jin, Song, Qi, Liang and Chen were also called the Six Dynasties, so Nanjing was called the "ancient capital of the Six Dynasties". Today, the site of Jiankang City is preserved under the Nanjing Library and the Six Dynasties Museum.

China ancient culture was preserved in Nanjing by the Han nationality through the southern crossing of Yiguan. During the Six Dynasties, Nanjing and Rome were both called "the two centers of world classical civilization", and the culture of the Southern Dynasties, represented by Jiankang, had a far-reaching influence in human history.

After the Six Dynasties, the Southern Tang Dynasty, the Ming Dynasty, the Taiping Heavenly Kingdom and the Republic of China successively made Nanjing the capital, so Nanjing was also called the "City of Ten Dynasties", leaving a rich cultural heritage.

Nanjing now uses the ancient capital of the Six Dynasties to show its early prosperity. Although the capital of the Six Dynasties was not established for a long time, in history, the Six Dynasties period was an important turning point of China culture, which achieved artistic integration for the first time and reached a peak.
