Other than Beijing, Shanghai and Tianjin, what other major city is one of China's four direct-controlled municipalities, and is also the birthplace of Chinese rally driver, Liu Caodong?
Liu Caodong Liu Caodong (刘曹冬, 22 February 1985 – 8 June 2011) was a Chinese rally driver born in Chongqing. He won the Chinese Rally Championship (CRC) in 2004，2006，2008 and 2010. In 2010, Liu contested in the World Rally Championship (WRC) with the Stobart M-Sport Ford Rally Team driving a Ford Focus RS WRC 08, co-driven by Australian Anthony McLoughlin. His name was misspelled as “Liu Chao Dong” on the entry list. That was the first time that a Chinese driver had driven a World Rally Car in the championship. He died of a cerebral edema caused by hypoxia alcoholism in 2011 at the age of 26.
Shanghai Metro The Shanghai Metro is a rapid transit system in Shanghai, China, operating urban and suburban rail transit services to 13 of its 16 municipal districts (except Fengxian, Jinshan and Chongming) and to Huaqiao Town, Kunshan, Jiangsu Province. Opening in 1993 with full-scale construction extending back to 1986, Shanghai Metro is the third oldest rapid transit system in China, after the Beijing Subway and the Tianjin Metro. It has seen substantial growth, significantly during the years leading up to the 2010 Shanghai World Expo, and is still expanding, with its most recent expansions having opened in April 2016. It is the largest component of the Shanghai metropolitan rail transit network, together with the Shanghai Maglev Train, the Zhangjiang Tram and the China Railway-operated commuter rail services to Jinshan and to Lingang New City in Pudong. The metro system is also heavily tied with other forms of public transport in Shanghai.
