Of the domestic cities, of course, the high level is the municipality, but municipalities already belong to the provincial level. Below the municipality, it is the sub-provincial level. There are currently 15 sub-provincial cities in China, of which 10 are provincial capital cities (Guangzhou, Nanjing, Wuhan, Shenyang, Xi'an, Chengdu, Jinan, Hangzhou, Harbin, and Changchun) and five cities with separate plans (Shenzhen, Dalian, Qingdao, and Xiamen Ningbo). There is also a city in China that is relatively low-key, but its strength should not be underestimated. This city is Wuxi known as the "Pearl of Taihu Lake."
