Provinces of China
Provincial-level administrative divisions () or first-level administrative divisions (), are the highest-level Chinese administrative divisions. There are 34 such divisions, classified as 23 provinces (), four municipalities, five autonomous regions, and two Special Administrative Regions. All but Taiwan Province and a small fraction of Fujian Province (currently administered by the Republic of China) are controlled by the People's Republic of China.
List of administrative divisions of Hainan
Hainan uses a slightly different administrative system from the other provinces of China. Most other provinces are divided entirely into prefecture-level divisions, each of which is then divided entirely into county-level divisions, which generally do not come directly under the province. 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's planned that the counties and cities in Hainan（excluding Sansha）would be merged into five city-level cities,just as those on the mainland area of China administratived by PRC.
