History of Haikou
The hanzi characters comprising the city’s name, 海口, mean ocean/sea and mouth/port, respectively. Thus, the name “Haikou” is also a word for “seaport” – similar to Portsmouth in England. Haikou originally served as the port for Qiongshan, the ancient administrative capital of Hainan island, located some 5 km (3.1 mi) inland to the south east. During its early history Haikou was a part of Guangdong province. In the 13th century it was fortified and became a military post under the Ming dynasty (1368–1644). The port is located west of the mouth of the Nandu River, Hainan’s principal river. When Qiongshan was opened to foreign trade under the Treaty of Tianjin in 1858, Haikou started to rival the old administrative city. It was known internationally as ‘Hoihow’, based on the local dialect. In 1926, Haikou overtook Qiongshan in population and it was declared a separate administrative city. Haikou was developed as a port during the Sino-Japanese War (1937–45) when the Japanese invaded and occupied Hainan Island from early 1939 to 1945.
The city and island of Hainan stayed under the control of the Nationalists until April 1950, when it fell to the Communists during the Landing Operation on Hainan Island.
Since 1949, Haikou has maintained its position as Hainan’s main port, handling more than half of the island’s total trade. It has replaced Qiongshan as the island’s administrative capital. In 1988, Haikou was made a prefecture-level city as well as the capital of the newly created Hainan Province.
Haikou old town contains the oldest buildings in the city and was largely built by wealthy Chinese from the mainland and some “overseas Chinese” who had returned to their homeland. The houses are a mixture of styles including Portuguese, French, and Southeast Asian. The streets used to be divided into different areas selling Chinese and western medicine, for silk and bespoke clothes, one for fresh fish and meat, and others for the sale of incense, candles, paper, ink, and other goods.
Various projects are currently under discussion to decide the best way to restore and preserve these historical buildings.
