It is one of four counties of Hainan. Its postal code is 571900. In 2002, its population was 490,800.[2] HistoryThe first record of Chengmai County is in 110 BC, when it referred to as Guo County in one of Emperor Wu of Han's records. The county acquired its current name under the Sui Dynasty reorganisation of 607. It was also recorded during the Ming Dynasty. GeographyLocated in northwest Hainan, it is {{convert|56|km|abbr=on}} wide (east to west) and {{convert|70|km|abbr=on}} long (north to south). It has a total land area of {{convert|2067.6|km2|abbr=on}}. Climate-wise, it is tropical with ample sunshine and moderate rainfall all year round; on average, the county receives 2060.5 hours of sunshine and {{convert|1756|mm|abbr=on}} of rain each year. The average annual temperature is {{convert|23.7|°C}}.[3] With a total land area of {{convert|206.7|km2|abbr=on}}, melons and other tropical crops are grown around the county. More than 20 rivers flow through the county, providing {{convert|17.4|e9m3|abbr=on}} of water per year. Jinjiang TownThe main settlement in the county is Jinjiang. It is located directly on the north side of the Nandu River and essentially occupies the south face of a large hill. The old section is located by the river with newer buildings further up. The backside of the hill is currently under development with mostly high-rise apartments being built. Many government buildings are situated on the top of the hill. Near the centre of the hill, there is a large park. EconomyThe main industry is mining, with more than ten resources available within the county including quartz, stone, limestone, crystals, gold, silver, peat, zinc, aluminium, iron ore, kaolin, and manganese. Over 5 billion tonnes of quartz are still unmined in the county, with an average grade of 99.5% silicon. There are also nearly 11 million tonnes of limestone remaining in addition to crystal deposits {{convert|5.5|km|abbr=on}} long and {{convert|3|km|abbr=on}} wide and around 80,000,000 tonnes of kaolin.

Apart from farm fishing, marine catches include mackerel, redfish, croaker fish, grouper, pomfret, tuna, squid, cuttlefish, lobster and shrimp, are fished in the harbour at Tu Beach. The diverse and populous fish are a result of a nutrient-rich sediment at the bottom of the harbour. DemographicsThe Han people account for 99.5% of the population of the county.
