Introduction to the Frost Descent Solar Term

Around October 23rd of the Gregorian calendar every year, when the sun reaches 210 degrees of the ecliptic longitude, it is the Frost Descent, one of the 24 solar terms. Frost Descent is the last solar term in autumn and the transitional solar term from autumn to winter. In late autumn, the ground dissipates a lot of heat and the temperature suddenly drops below 0 degrees. The water vapor in the air directly condenses on the ground or on plants to form tiny ice needles. Some become hexagonal frost flowers, which are white in color and have a loose structure.
In mid-September, the weather becomes cold and condensed, and the dew turns into frost. At this time, white frost has appeared in the Yellow River Basin of China. Silver ice crystals are shining brightly on the thousands of miles of fertile fields. At this time, the leaves are yellow and falling. The ancient book “Explanation of the Twenty-Four Solar Terms” says: “When the weather is cold and frost falls, yin begins to condense.” It can be seen that "Frost Descent" means that the weather is gradually getting colder and the dew condenses into frost.
In ancient my country, Frost Descent was divided into three stages: the first stage was when jackals offered sacrifices to animals; the second stage was when grass and trees turned yellow and fell; the third stage was when stinging insects all lay down. The jackals begin to capture prey and sacrifice animals, using animals to offer sacrifice to heaven in return for their origins, and also to offer sacrifice to the autumn gold; the leaves on the ground turn yellow and fall; the stinging insects all stay in their holes, motionless and uneaten, with their heads down, entering hibernation.

Frost Descent Customs in Various Places:

Hunan: In October, Cold Dew and Frost arrive, and people harvest late rice and dig potatoes.
Shanghai: The Cold Dew in October is followed by the Frost Descent, and we are busy with autumn harvest, autumn planting and winter work. The late rice is threshed and the cotton is turned over and dried, and it is carefully harvested and stored. In Anhui, after the harvest in Cold Dew, the land is turned over by Frost Descent.
Shanxi: During the Cold Dew season, we should start autumn ploughing and do not slack off during the autumn harvest and planting. Cotton picking, potato digging, wheat stubble and autumn irrigation are all underway. Irrigate the land, plant trees and collect fodder, and exchange yam seeds in other places.
Hebei: Cold Dew and Frost Descent, harvesting soybeans. Hurry up and put the products into storage in time. Late wheat, surprise sowing. Harvest mountain grass to feed livestock. Plant several acres of spinach and rapeseed. It can be harvested early next spring.
Shandong: When Frost Descent arrives, the weather starts to get colder. Hurry up and harvest the sweet potatoes and peanuts. Cut and dry the melons on a sunny day. Once the sweet potatoes are stored in the cellar, you can't relax. The condition of wheat seedlings in the field must be checked carefully. If there are missing seedlings or broken ridges, replant them in time.
