Hainan uses a slightly different administrative system from other administrative regions of China. In Hainan, nearly all county-level divisions (the eight districts excepted) come directly under the province. This method of division is due to Hainan's relatively sparse population. However, it is planned that the counties and cities in Hainan (excluding Sansha) would be merged into five city-level cities, just like those in mainland China.
