It belongs to the subtropical monsoon climate zone, with an average annual temperature of about 15 degrees. It faces the water on three sides and the land on the other, and is adjacent to Shanghai and Suzhou. It has jurisdiction over Chongchuan District, Gangzha District, Fumingang Economic and Technological Development Zone, Langshan Tourist Resort, Qidong, Haimen, Tongzhou, Rugao and Hai 'an and Rudong counties. The total area is 8,111 square kilometers and the population is 7.89 million. The urban area is 224 square kilometers and the population is 741,111.

In ancient times, Nantong was a vast estuary sea area. With the sediment deposition of the Yangtze River, sandbars, shoals and land gradually formed. Hai 'an County was the earliest land. Five or six thousand years ago, there was human life in Qingdun, Hai 'an. Rugao City and Rudong County were successively connected with the land in the Han Dynasty and the Southern and Northern Dynasties. By the Han Dynasty, local people began to "cook the sea for salt" and became famous salt-producing areas in history. However, Nantong City and Tongzhou City were still continents in the Northern and Southern Dynasties, and they were called Hudouzhou, which was not connected with the mainland until the end of the Tang Dynasty. As Hudouzhou is an important producing area of sea salt, Langshan Town was set up in 875, the second year of Tang Xizong Ganfu. During the Five Dynasties and Ten Kingdoms period, Jinghai Town was established in the Southern Tang Dynasty. In 958 AD, the Northern Zhou Dynasty sent troops south to occupy the Jinghai, and built a city, which was upgraded to a static navy and transformed Tongzhou, named after its geographical location extending in all directions. After the Revolution of 1911, the Republic of China was established (1912), and the abandoned state was set up as a county. In order to distinguish it from Tongzhou (commonly known as North Tongzhou) in Hebei Province, it was renamed Nantong County, and the name of Nantong began here. In February 1949, Nantong was liberated, and Nantong City was built. Nantong County remained, and the county was moved to jing sha (now Nantong County was renamed Tongzhou City), and the city and county were divided. In 1983, Nantong city and Nantong area merged and implemented the system of city governing county, which constituted today's new map.

it is known as the hometown of education, the hometown of longevity, the hometown of Olympics and the first city in modern China.

because the economy is located in the north of the Yangtze River, its development has been affected. At present, it is in the middle reaches of Jiangsu, and its development momentum has soared, which has the strength to catch up with Suzhou and Wuxi.
