The People's Republic of China is officially divided into 23 provinces, five autonomous regions (each with a designated minority group), and four municipalities—collectively referred to as "mainland China"—as well as the special administrative regions (SARs) of Hong Kong and Macau. Geographically, all 31 provincial divisions of mainland China can be grouped into six regions: North China, Northeast China, East China, South Central China, Southwest China, and Northwest China.
