參考答案:南京
Nanjing is the capital of China's Jiangsu Province and a city with a prominent place in Chinese history and culture. Nanjing has served as the capital of China during several historical periods, and is listed as one of the Four Great Ancient Capitals of China. Nanjing is also one of the fifteen sub-provincial cities in China's administrative structure, enjoying jurisdictional and economic autonomy only slightly less than that of a province. In addition, the Republic of China, which controls Taiwan and neighbouring islands, claims it as its de jure capital.
Located in the downstream Yangtze River drainage basin and Yangtze River Delta economic zone, Nanjing has always been one of China's most important cities. Apart from having been the capital of China for six dynasties and of the Republic of China, Nanjing has also served as a national hub of education, research, transportation and tourism throughout history. It is also the second largest commercial center in the East China region, behind only Shanghai.

Nantong is a prefecture-level city in Jiangsu province, People's Republic of China. Located on the northern bank of the Yangtze River near the river mouth, Nantong is a vital river port bordering Yancheng to the north, Taizhou to the west, Suzhou to the south across the river, and the East China Sea to the east.
Because the coast of the East China Sea is constantly moving eastward as the Yangtze River adds silt to its delta, Nantong was much closer to the seashore in ancient times. From the time of the Han dynasty through to the Tang dynasty, what is now called Nantong was a minor county subordinate to Yangzhou. By 958 AD a city of sufficient importance had developed for a new, independent prefecture called Tongzhou ("Opening Prefecture", possibly from its position near the mouth of the Yangtse) to be created. The increasing wealth of Yangzhou caused Tongzhou to be once again eclipsed as an administrative center in 1368. When Tongzhou finally regained prefecture status in 1724, it was renamed Nantong ("Southern Tong") to avoid confusion with another Tongzhou, located near Beijing.
The prosperity of Nantong has traditionally depended on salt production on the nearby seacoast, rice and cotton agriculture, and especially the production of cotton textiles. A local statesman and industrialist named Zhang Jian (Chang Chien) founded Nantong's first modern cotton mills in 1899, then developed an industrial complex that included flour, oil, and silk reeling mills, a distillery, and a machine shop. He also founded a shipping line and reclaimed saline agricultural land to the east of Nantong for cotton production. By 1911, Nantong was commonly called "Zhang Jian's Kingdom".
Although suffering from the economic depression of the 1930s and the Japanese occupation of the 1930s and 40s, Nantong has remained an important center for the textile industry. Because of its deep-water harbour and connections to inland navigational canals, it was one of 14 port cities opened to foreign investment in the recent economic reforms.
