What places are South China, East China, North China, Jianghuai, Huanghuai and so on in the central weather forecast?

South China: Physical geography generally refers to the area south of Nanling in China, including Guangdong, Guangxi, Hainan, Hongkong and Macau. Another argument is that Fujian and Taiwan Province provinces are also included in South China, which is slightly controversial.

East China: Geographically, it generally refers to the region where six provinces 1 cities in eastern China are located, including Jiangsu, Zhejiang, Anhui, Fujian, Jiangxi, Shandong and Shanghai. North China: generally refers to the area of two northern provinces and two cities in China 1, including Hebei, Shanxi, Beijing, Tianjin and parts of Inner Mongolia Autonomous Region. Jianghuai: refers to the vast areas north of the Yangtze River, south of the Huaihe River, east of Dabie Mountain and west of the Yellow Sea (mainly including most areas of Jiangsu and Anhui; And a few areas in Jiangxi, Hubei and Henan). Huanghuai: In a broad sense, it refers to all areas from the south of the Yellow River to the north of the Huaihe River. The Huanghuai area we want to study is slightly smaller than the generalized Huanghuai area, mainly referring to the southern foot of Yimeng Mountain, the north of Huaihe River, the east of Kaifeng and the vast area between the sea, excluding Funiu Mountain, Tongbai Mountain and the north of Yimeng Mountain. In other words, the Huanghuai area we want to study mainly refers to the Huanghuai Plain including eastern Henan, northern Anhui, southern Shandong and northern Jiangsu.
