Chongming (help·info) (simplified Chinese: 崇明县; traditional Chinese: 崇明縣; pinyin: Chóngmíng Xiàn; Wu: Dzonmin Jeu), formerly romanized as Tsungming, is the only county under the jurisdiction of Shanghai, China. The county consists of three main islands: Chongming (simplified Chinese: 崇明岛; traditional Chinese: 崇明島; pinyin: Chóngmíng Dǎo); Changxing; and Hengsha. These are low-lying alluvial islands in the mouth of the Yangtze. With an area of 1,041 square kilometres (402 sq mi), Chongming Island is the third largest island in Greater China after Taiwan and Hainan. 
Once the most rural area of Shanghai, it is now the subject of a major urban and agricultural master-plan led by Philip Enquist of Skidmore, Owings & Merrill. With the construction of a trans-Yangtze tunnel, the island is expected to increase in population while incorporating specialized agriculture in a sustainable design. It is also a major relocation centre for migrants from Three Gorges Dam area. Chongming has an area of 1,041.38 square kilometres (402.08 sq mi) and a population of 704,000 as of 2010. The Eco-city of Dongtan is being planned in the county. Dongping National Forest Park is also located in the county.
