Early textbooks (former Republic of China, now Taiwan Province Province, China) defined the scope of South China as: Guangdong, Guangxi, Guizhou, Yunnan, Fujian and Taiwan Province provinces, collectively known as "six provinces in South China".
According to the current administrative divisions and definitions, the narrow sense of "South China" usually refers only to Guangdong Province and Hainan Province, and sometimes includes two special administrative regions, Hong Kong and Macao.

Central and Southern China:
The geographical concept of Central South is rarely seen in traditional appellations, and it has been gradually used since modern times. It usually includes present-day Henan, Hubei, Hunan, Guangxi Zhuang Autonomous Region, Guangdong and Hainan provinces. Today, the predecessor of the southern theater of the Chinese People's Liberation Army is the Guangzhou Military Region, and its jurisdiction covers the above-mentioned provinces and regions. Later, Henan Province and Hubei Province were successively placed under the jurisdiction of today's Central Theater.
Today, the traffic atlas published in People's Republic of China (PRC) usually unifies the highway network between Henan Province and the two lakes, Guangdong, Guangxi and Hainan into "Central South Region".
