evidence: Mainland China, also called the Chinese Mainland, is the part of China not including the Republic of China controlling Taiwan, Kinmen, Matsu, and the Pescadores. The term also excludes Hong Kong and Macau. [...] Since then, Communist China only includes the part on the continent (mainland) and some small islands that are very near (the largest communist island is Hainan). This region is Mainland China. Later Hong Kong and Macau were returned to the government of China, but because the government calls them "special administrative regions" under a "one country, two systems" idea, they are still not thought of as part of Mainland China.
