Frost Descent:
Frost Descent is the eighteenth solar term among the twenty-four solar terms and the last solar term in autumn. It falls on October 23rd and 24th every year in the Gregorian calendar. After the frost, the late autumn scene is obvious, and the cold air moves southward more and more frequently. Frost does not mean "frost", but means a sudden drop in temperature and a large temperature difference between day and night. On the national average, "frost" is the season of the year with the largest temperature difference between day and night.
The frost festival mainly includes the customs of appreciating chrysanthemums, eating persimmons, climbing high and overlooking the distance, and taking supplements.
