Hangzhou (杭州; Hángzhōu) is in Zhejiang Province, China. It is one of the most important tourist cities in China, famous for its natural beauty and historical and cultural heritage. It is the political, economic and cultural center of Zhejiang province as well. It's worthwhile to know that it's extremely humid in summertime, which is from early June to early September.
Famed for its natural scenery, Hangzhou and its West Lake (西湖; Xīhú) have been immortalized by countless poets and artists. The city was the capital of the Southern Song Dynasty from 1127 until the Mongol invasion of 1276. The city's population is estimated to have been as high as one million in those days, making it the largest city in the world at the time. Even Marco Polo claimed to have passed through, calling it beyond dispute the finest and the noblest in the world. Since June 2011, the West Lake Cultural Landscape has been listed as a UNESCO World Heritage site. With the gradual silting up of its harbor, much of the city's trade and industry passed north to nearby Shanghai, but the city still has a bustling population of 8.7 million and ranks as one of China's most popular tourist attractions.
