Are the Yangtze River Basin and Jiangsu and Zhejiang Provinces the worst places in eastern China?

First, the eastern part of China includes Hebei, Beijing, Tianjin, Shandong, Jiangsu, Zhejiang, Shanghai, Guangdong, Hainan, Fujian, Taiwan Province, Hong Kong Special Administrative Region and Macao Special Administrative Region. (Excerpted from Baidu Encyclopedia). In terms of regional climate, typhoons are frequent in Guangdong, Fujian and southern Zhejiang, while precipitation in Beijing, Tianjin and Henan is less. These places are much worse than Jiangsu and Zhejiang in the middle and lower reaches of the Yangtze River (referring to Shanghai+northern Zhejiang, southern Jiangsu and southwestern Anhui along the Yangtze River). On the other hand, there is abundant rainfall in Jiangsu and Zhejiang provinces. Although there are not many climate disasters, floods are also buffered by Hunan, Hubei and Jiangxi in the middle reaches. The average annual sunshine time is neither too high nor too low. Therefore, in ancient times, there was a saying that the soil and water in Jiangnan were good for raising people. It's rainy in April, wet and cold in winter, no heating, etc. , although annoying, but really not bad ...)
