Emperor Wendi of Sui wrote: "Shizhen is located in Jiangzhou." Jiangzhou is named after Shan Jiang. Shan Jiang is the name of Wu Dongzi Jinshan. In the Han Dynasty, Purple Mountain was described by Mr. Feng Shui as "the place where Wang Qi gathered", so it was named Zhongshan. Now, in order to avoid the taboo of Sun Quan's grandfather, Jiang, who died in Zhongshan at the end of the Eastern Han Dynasty, was renamed. So only Stone Town is left as Jiangzhou City, which governs Jiangning, Lishui and Dangtu counties.
In the second year of Yang Di Daye (606), Jiankang County, Xia Tong County and Moling County were merged into Jiangning, Linyi County, Danyang County and Hushu County were abolished, and their territories were also merged into Jiangning. The following year, Jiangzhou was renamed Danyang County, and Jiangning and Lishui still belonged to Danyang County.
The Sui Dynasty consciously carried out the policy of restraining Jinling and destroyed the cities and palaces of Jiankang in the Six Dynasties. However, the Tang Dynasty continued to implement the policy of restraining Jinling, which made the urban construction in this area not develop much, but Jinling was still an important town and economic and cultural center in southeast China at that time.
In the ninth year of Tang Wude (626), Yangzhou, an administrative organization located in Shicheng, moved to Jiangdu (now Yangzhou), and Jinling was successively called Jiangzhou and Yangzhou. In the Tang Dynasty, Nanjing used the names Danyang, Jiangning, Osmanthus fragrans, Baixia and Shangyuan.
In the third year of Tang Wude (620), Du returned to Tang with Jiangnan. In the Tang Dynasty, Yangzhou was established in Jiangning and Lishui counties, and Jiangning was changed to Guihua county. Pingfu Gongyou changed Yangzhou to Jiangzhou in seven years and Yangzhou in eight years. At the end of the same year, he moved to Yangzhou and ruled the state in Hanjiang (now Jiangdu, Yangzhou). In eight years, Guihua County was changed to Jinling County, and in nine years, it was changed to Baixia County, which belongs to Runzhou. Zhenguan nine years (635) was changed to Jiangning County. In the second year of Zhide (757), Jiangning County was established in Jiangning County. In the first year of Gan Yuan (758), Jiangning County was changed to Shengzhou. In the second year of Shangyuan (76 1), Jiangning was changed to Shangyuan County. Baoying was abolished in the first year (762) and was promoted to the state. In the third year of Guangqi (887), he moved the capital to Shengzhou.
After the mid-Tang Dynasty, many famous poets came to Jinling to visit and pay their respects, and created a considerable number of poems about "nostalgia for Jinling", among which Cui Hao, Li Bai, Liu Yuxi, Du Mu, Li Shangyin and Wei Zhuang were the most famous, which reflected the social outlook of Nanjing at that time.
