Folklore takes "beginning of winter" as beginning of winter, but in fact, China has a vast territory. Winter doesn't start at the same time except in the coastal areas of South China where there is no winter all the year round and the Qinghai-Tibet Plateau where there is no summer in long winter.

After beginning of winter, the sunshine time will continue to shorten, and the height of the sun will continue to decrease at noon. In winter, northeast winds and north winds prevail, and the temperature drops gradually. Because there is still some energy in the heat stored on the surface, it is generally not very cold in early winter. As time goes by, strong cold air frequently goes south and crosses Nanling, and the weather is getting colder and colder. In the north, it is already very cold before winter begins.

Traditionally, "beginning of winter" is the beginning of winter, "Spring comes and summer grows, autumn harvests and winter hides". Winter is the season to enjoy harvest and rest.
