What is the origin of slight cold in the twenty-four solar terms?

1 Of the 24 solar terms, slight cold is the 23rd solar term, which is used to indicate the change of temperature. At this time, the weather is already very cold, which corresponds to the slight heat in summer, so it is called slight cold.

2. When the winter solstice passes, the days become longer, but at this time, the temperature has not risen, and it has entered the coldest stage of the year. At this time, people no longer go out to farm, but stay at home to warm themselves and have a good rest to save energy for the arrival of spring.

Because everyone stays at home to keep warm in the slight cold season, there are many traditional customs to do. In addition, the blooming of plum blossoms adds a lively atmosphere to the slight cold solar terms, and eating Laba porridge, which we are familiar with, is also carried out in the slight cold solar terms.

At this time, the temperature is the lowest, and the river has frozen. In areas where the ice layer is particularly thick, most of them have ice beds for pedestrians to play with, and some even race on the ice with skates, which was called ice play in ancient times.
