Douban.com (Chinese: 豆瓣; pinyin: Dòubàn), launched on 6 March 2005, is a Chinese online database and social networking service that allows registered users to record information and create content related to film, books, music, recent events, and activities in Chinese cities. Douban is named after a hutong in Chaoyang District, Beijing where the founder lived while he began work on the website. Douban was formerly open to both registered and unregistered users. For registered users, the website recommends potentially interesting books, movies, and music to them in addition to serving as a social network website such as WeChat, Weibo and record keeper. For unregistered users, the website is a place to find ratings and reviews of media. Douban has about 200 million registered users as of 2013 and some Chinese authors as well as critics register their official personal pages on the site. The platform has been compared to other review sites such as IMDb, Rotten Tomatoes and Goodreads. Source: Wikipedia (en)
