query: How provinces are there in China?
passage: Provinces of China
Provincial-level administrative divisions (Chinese:省级行政区; pinyin:shěng-jí xíngzhèngqū) or first-level administrative divisions (一级行政区; yī-jí xíngzhèngqū), are the highest-level Chinese administrative divisions. There are 34 such divisions, classified as 23 provinces (Chinese:省; pinyin:shěng), 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.
passage: South China
In normal parlance and geography, it refers to the region south of the Qinling Huaihe Line.
In the broadest sense, Southern China can denote the entire portion of the country south of the line demarcated by the Qin Mountains and Huai River. Between 1945 and 1949, the Republic of China defined Guizhou, Yunnan, Guangdong, Guangxi, Hainan, Fujian and Taiwan as the "Seven Provinces of South China" (). The term can also be used to denote the Lingnan region; but today, the phrase is generally used to refer only to Guangdong, Guangxi, Hainan, Hong Kong and Macau (historically also known as Liangguang). Defined as such, South China is also contained within South Central China.
