Chéngmài

Chéngmài is an old county town on the northern coast of Hainan. Established under the Sui in 607, the county took its name from the Chéng River and Mài Mountain. Its seat lay at Chéngjiāngpō, near the coast and the routes leading to Qióngzhōu. The town became one of the island's established market centres, while the old post roads and bridges of the district connected it with other settlements around northern Hainan.
