The Great Cold is the last of the 24 solar terms. After the severe cold, beginning of spring will usher in a new year's solar cycle. The Spring Festival is just around beginning of spring. As soon as it gets cold, the flavor of the New Year becomes stronger and stronger. The severe cold solar terms often coincide with the end of the year, and some folk customs during the period have more meaning of saying goodbye to the old and welcoming the new.

In this solar term, people are busy saying goodbye to the old and welcoming the new, pickling new year's dishes and preparing new year's goods, because the Spring Festival, the most important festival for China people, is coming. As the last solar term at the end of the year, the Great Cold is a slack season, but everyone is "busy"-busy with the New Year, which is the custom of "welcoming the New Year in the Great Cold".

The so-called "welcome in the cold" means that during the period from the cold to the Lunar New Year, there will be a series of activities among the people. In summary, there are at least ten customs, namely, eating glutinous rice, binge drinking, making teeth, sweeping the dust, pasting windows, tasting bacon, catching a wedding, going to the market and bathing.
