What does it mean to be foggy in May?

If there is no heavy rain, it indicates that the weather will be dry, and even a gourd can be planted at the bottom of the well.

May of the lunar calendar is June of the solar calendar, which is the end of the flood season in our province. Before the end of the flood season, there are often heavy rains. After entering the flood season, our province was controlled by subtropical high, and there was a long period of sunny, hot and high temperature weather. According to the general rule, fog appears in May, which indicates that the river will rise under heavy rain.

But sometimes there is fog, but there is no heavy rain, which means that there was less rain in that year, and even less rain after the rainy season. In this way, it is not impossible to plant a gourd at the bottom of the well.
