Phenological phenomenon of Xiaoman in 2022;

Wu Cheng, a scholar in Yuan Dynasty, edited Twenty-four Solar Terms. According to the scenery around the Yellow River Basin and the characteristics of the twenty-four solar terms, he divided the twenty-four solar terms into "seventy-two periods", and each solar term was divided into three periods. Xiaoman waited three times: "Wait for the bitter vegetable show, wait for the grass to wither, and wait for the wheat autumn."

In other words, after the full solar terms, bitter vegetables have flourished; After that, some soft grass with shady branches began to die in the strong sunlight; In the last period of Xiaoman, wheat began to mature.

The third period was originally written about the summer solstice, and later some works were changed to the winter solstice of wheat. Although it is still summer, it is a mature "autumn" for wheat. Summer is the season when winter wheat matures in the north, and autumn is the season when grain matures, so the ancients extended the name of early summer to wheat autumn.
