What are the characteristics of Xiaoman solar terms?

During the Xiaoman solar term, there is usually a lot of rainfall in southern China.

Warm and humid air from the ocean is active and meets cold air from north to south. At this time, there will often be sustained and large-scale heavy precipitation in South China, causing heavy rain or torrential rain.

Jiangnan area, are often rivers and lakes. If there is little rain at this stage, it may be that the Pacific subtropical high is weak and located in the south, which means that it is Huangmei season. In the north, there is little or no rain in the solar terms, during which the temperature rises rapidly and the temperature difference with the south further narrows.

According to the characteristics of farming society, the folk customs of solar terms in Xiaoman mainly include "offering sacrifices to car gods", "moving three cars (water wheel, oil car and silk car)", "grabbing water for Xiaoman", "praying silkworms for Xiaoman" and "eating wild vegetables for Xiaoman".

The Historical Origin of Xiaoman Solar Terms

"Twenty-four solar terms" is a special festival in the calendar to express the change of natural rhythm and establish "December architecture", which can accurately reflect the change of natural rhythm and contains a long cultural connotation and historical accumulation.

The climate of Xiaoman solar term is characterized by frequent precipitation, which often leads to continuous large-scale heavy precipitation. In the southern region, the "fullness" in the small fullness refers to the excess rain. "Full" comes from water, which means "overflow".

For example, Shuo Wen Jie Zi says, "Man, Man." Small solar terms, the South China Sea summer monsoon broke out, the rain in South China gradually increased, and the river was so small that it was full. This is the time to store water and plant rice. If there is little rain at this time, it is the so-called "small full of dissatisfaction, dry up the ridge" and "small full of dissatisfaction, regardless of the seeds" in agricultural proverbs.

In other words, when the field is full, there is not enough water, which may cause cracks in the ridge, and even rice cannot be planted when planting. After the Xiaoman solar term, due to the influence of the South China Sea summer monsoon, the heavy precipitation in South China will increase obviously, and the rivers will gradually fill up.
