Xiamen is one of the top 100 cities in the world by scientific research as tracked by the Nature Index. In 2006, Xiamen was ranked as China's second-"most suitable city for living", as well as China's "most romantic leisure city" in 2011. The city is well known for its mild climate, Southern Min culture and Gulangyu Island, as well as its relatively low pollution. Its former harbor was enclosed using land excavated during the city's expansion, however, the city remains an island connected by bridges to the rest of mainland China. As part of the Opening Up Policy under Deng Xiaoping, Xiamen became one of China's original four special economic zones opened to foreign investment and trade in the early 1980s. The overseas Chinese continue to support Xiamen's educational and cultural institutions. Under the Qing, both before and after the First Opium War, there was a large-scale emigration of Chinese from southern Fujian who spread Hokkien-speaking communities to Singapore, Malaysia, Indonesia and the Philippines. Xiamen Island possessed a natural harbor in Yundang Bay, but Fujian's international trade was long restricted to Quanzhou or to Guangzhou in Guangdong. The Kinmen Islands (Quemoy) administered by the Republic of China lie less than 6 kilometers (4 mi) away. This area also connects with Quanzhou in the north, making up a metropolis of nearly ten million people. The urbanized area of the city has spread from its original island to include most parts of all six of its districts, and with 4 Zhangzhou districts ( Xiangcheng, Longwen, Longhai and Changtai), form a built-up area of 7,284,148 inhabitants. All together, these cover an area of 1,700.61 square kilometers (656.61 sq mi) with a population of 5,163,970 as of 2020 and estimated at 5.18 million as of 31 December 2020. It is divided into six districts: Huli, Siming, Jimei, Tong'an, Haicang, and Xiang'an.
