The Xiaoman solar term occurs between May 20th and 22nd of the Gregorian calendar every year. Xiaoman occurs in summer and is the second solar term in summer. The arrival of Xiaoman means that the crops begin to be full of grain filling, and the sun reaches 60 degrees of the yellow meridian, which is the longest time node in the daytime in a year.
The origin of xiaoman solar terms
Every year from May 20 to 22, when the sun reaches the yellow diameter of 60, it is full, which is the beginning of hot summer and the time when diseases are easy to appear. The name "Xiaoman" comes from crops. The seeds of summer crops began to be full, but not yet mature, just small and not yet full.
"twenty-four solar term": "In mid-April, things are small and full." At this time, the seeds of summer crops such as wheat in the northern part of the country have begun to be full, but they are not yet mature, which is about the late stage of milk ripening, so it is called Xiaoman. Agricultural proverbs in the southern region give Xiaoman a new meaning: "Xiaoman is dissatisfied, and he thinks about it"; "Small full of dissatisfaction, regardless of the mango." The term "full" is used to describe the surplus and shortage of rain, and it is pointed out that if there is not enough water in the field when it is full, the ridge may be cracked, and even rice cannot be planted when it is planted.

Climatic characteristics of xiaoman
1. Climate characteristics in southern China
Generally speaking, during the Xiaoman period, the active warm and humid airflow in the south meets the cold air from the north to the south in South China, and then there will often be continuous and large-scale heavy precipitation in South China. Therefore, the later period of Xiaoman solar term is often the tense stage of flood control in these areas.
2. Climatic characteristics of the northern region
The arrival of Xiaoman means that the northern region will enter the longest sunshine period. Because it is much easier to heat dry air in the north than wet air in the south at this time, the temperature difference between the north and the south is further reduced when it is full.
