Shenzhen (Chinese: 深圳市; pinyin: Shēnzhèn Shì) is a city of sub-provincial administrative status in southern China's Guangdong province, situated immediately north of Hong Kong. Owing to China's economic liberalization under the policies of reformist leader Deng Xiaoping, the area became China's first—and arguably one of the most successful—Special Economic Zones. Being southern mainland China's major financial centre, Shenzhen is home to the Shenzhen Stock Exchange as well as the headquarters of numerous high-tech companies. Shenzhen is also the second busiest port in mainland China, ranking only after Shanghai.For more info,please refer to :http://en.wikipedia.org/wiki/Shenzhen.
