No sunshine for three days and three feet refers to which province?

The ground is not three feet flat, and the sky is not sunny for three days, which refers to Guizhou Province.

Because Guizhou Province has been a mountainous area since ancient times, there are almost no plains here, so the terrain is very rugged, and there is a saying that "the ground is not three feet flat". As a mountainous area in Guizhou Province, the weather here is very humid, so there are few sunny days. Later, the saying "no sunny days" was formed.

The climate type of Guizhou belongs to subtropical monsoon climate. Influenced by the southeast monsoon and southwest monsoon, summer is the main rainy season, with less precipitation in spring and autumn, while winter, under the monsoon climate, should be the season with less precipitation, but it is different in Guizhou. Therefore, the "three sunny days" in Guizhou mainly means that it often rains in winter in Guizhou, which is relatively humid and cold and has a poor sense of body.

There is no sunny day without three feet, which comes from Zhu Guozhen's sketch "Yongtong Sketch" in the Ming Dynasty. The word "money" which describes "rainy in Guizhou" refers to Guizhou. One of them described the rainy weather and rugged mountain roads in Guizhou. As the poorest province in China, there are people who end this sentence with "no one has three cents".
