The so-called “Xiaoman” is so small that it is full, the sun is warm but not intense, and the river is full but not overflowing. For the south, the Xiaoman solar term is often the time when rivers and lakes are full. “Full” refers to the abundance of rain. During the Xiaoman season, the rainfall is large, and the rivers are so small that they are full.

South China is in the peak of the pre-flood season, and the process of heavy precipitation is often seamlessly connected; while in the north, there is little or no rain at this time.

From the perspective of the whole year (1991-2020), after entering the Xiaoman solar term, the north starts the dry and hot season, enters the “exposure mode”, and the temperature rises rapidly.
