Phenological phenomenon

Beginning of winter means that everything begins to enter a state of recuperation. Wu Cheng, a scholar in Yuan Dynasty, edited Twenty-four Solar Terms. He divided the twenty-four solar terms of a year into "seventy-two periods", and each solar term was divided into three periods. The three periods in beginning of winter are: "When water begins to freeze, the second period begins to freeze, and the third period is flood."

Explain that at this time, the water has turned into ice and the land has begun to freeze. The pheasant in the flood refers to the pheasant and other big birds, and the pheasant is a giant clam. After beginning of winter, pheasants and other big birds were scarce, but giant mussels with similar lines and colors could be seen at the seaside, so it was thought that pheasants would become giant mussels when they arrived in beginning of winter.
