Underground City - China

China

• Beijing built an extensive tunnel network called the Underground City (Chinese: 地下城; pinyin: Dìxià Chéng) during the Sino-Soviet conflict, supposedly covering 85 km², falling into disuse in the 1970s. It has been recently opened to the public and tourists. There are rumors it was used by the army during the Tiananmen incident.

• Shanghai has a few underground networks, most notably at the People's Square metro station, wherein the line 2 station has a second mezzanine full of shops and line 1 is connected to a large underground shopping gallery at its south end. Shanghai Science Museum stop on line 2 has a large underground shopping area, known for its imitation goods. Huangpi Road South and Xujiahui stations are directly connected to shopping centers, and the Lujiazui station is connected to the Bank of China tower.
• Qingdao has two small underground shopping areas, one at the head of the Zhanqiao (pier) and one west of the Qingdao guest house.
• Harbin has a number of large, multi-level underground shopping areas, originally built for air defence. The largest is at the roundabout intersection of Xida Zhi street and Hongjun street where three levels of markets following streets from four directions meet under the giant snowflake atrium.
