Historical evolution

In 1928, Qidong was named after "Qiwu Dongjiang" because of the continuous eastward extension of sandbanks.

Han, the Yangtze River Estuary.

In the early Tang Dynasty, Dongzhou and Buzhou rose out of the Yangtze River Estuary. During the reign of emperor Wude of Gaozu, the Yangtze River Estuary became an island in the middle of the river. Prisoners were exiled here to engage in salt production. It belongs to Guangling County as well as Hu douzhou (today's Nantong urban area, Pingchao and Xiting town of Tongzhou), which is subordinate to Huainan road.

In 907, Dongzhou and Buzhou in the Yangtze Estuary merged into Haimen island. In the first year of Later Zhou Xiande (954), there was a local management organization named lvsichang, which was set up in the first place of politics and occasions. After Zhou Xiande five years, set Haimen County in dongbuzhou, Li Tongzhou. Haimen county includes the central and northern parts of Qidong.

From song to he (the middle of the 11th century), huduozhou expanded eastward and connected with Haimen Island, forming a "tonglvshui ridge" about 75 km long from east to west and 20 km wide from north to South (near Tangzha town in the West and Lvsi town in the East).

From the end of the Yuan Dynasty to the middle of the Ming Dynasty (14th-15th century), the main channel of the Yangtze River moved northward, and a large area of Haimen along the river collapsed, leaving only lvsiyi.

In 1672, Haimen county was abolished and changed into Haimen Township, which was incorporated into Tongzhou. Tongzhou (Nantong county) governs the Lvsi area in the northeast of today's Qi. At the end of Kangxi period, the North Bank of the Yangtze Estuary began to deposit. Many small sandbanks gradually merged to form Qihai land. In 1768, there were 19 sands in Tongzhou, 11 sands in Chongming and 10 sands in Xinzhang. The Haimen Zhili hall was set up and attached to the Department of Jiangsu's chief envoy. Today, the central region of Qidong is the east of Zhili hall in Haimen.

From Yongzheng to the early years of Guangxu (1723-1875), 13 sandbanks such as huiansha, yangjiasha and yongfengsha on the North Bank of the Yangtze River Estuary were formed and connected one after another. Because they are close to Chongming, they are called outer sandbanks of Chongming (Chongming Island is called inner sandbanks).

Guangxu 23 years (1897), Chongming County set up Chonghai inspection department in Jiulong Town (Jiulong Town). The boundary of Chonghai is the outer sand of Chongming in Henan, and Haimen in the north. To the south of Tonghai boundary river is Haimen, and to the north is Tongdong (east of Tongzhou Zhili).

In January of the first year of the Republic of China (1912), Haimen county was established. In May, Tongzhou was renamed Nantong county. Today, the central region of Qidong belongs to Haimen County, which belongs to huhaidao; the northern region belongs to Nantong County, which belongs to Suchang road.
