Beihai is a prefecture-level city in the south of Guangxi, People's Republic of China. The name of the city means "north of the sea" in Chinese, signifying its status as a seaport on the north shore of the Gulf of Tonkin, which has granted it historical importance as a port of international trade for Guangxi, Hunan, Hubei, Sichuan, Guizhou, and Yunnan. After the 1876 Sino-British Treaty of Yantai, eight Western nations (UK, US, Germany, Austria-Hungary, France, Italy, Portugal, and Belgium) set up embassies, hospitals, churches, schools, and maritime customs. There is an excellent beach and lots of cheap food, including Vietnamese food since many refugees came here. The weather is warm for most of the year, however during winter months it is not warm enough to work on your tan on the seafront.
