Dadukou District.

Dadukou is one of the twelve central urban clusters of Chongqing, on the south-west bank of the Yangtze, facing Nan'an and Banan across the water and bordering Jiulongpo, the high-tech zone and Shapingba. On 2 April 1965 the Jiugongmiao, Xinshancun and Yuejincun subdistricts were cut out of Jiulongpo to form the Dadukou industrial district, and in 1995 it grew from 7.46 to 103 square kilometres by taking Xiqiazi, Baqiao and Jiansheng from Jiulongpo and Tiaodeng from Banan. It is an important base for metallurgy and building materials. Line 2 has run from Xinshancun to Jiaochangkou since 28 June 2006.
