Why does Guiyang rain like winter?

This season in Guiyang is a rainy season, which is influenced by the quasi-static wind in Kunming, forming frontal rain and forming a long-term rainfall process. Meiyu originally refers to the long rainy season in May south of the Yangtze River, which coincides with the plum ripening season. Therefore, it is called "Meiyu". The same is true of the climate phenomenon in Guiyang. Therefore, in ancient times, there was a saying that it would be sunny for three days.
