What does the 21st day of the first month mean?

As the saying goes, "wear it on the twentieth day of the first month, and wear it on the twenty-first day of the first month", which means that the twentieth day of the first month is the day to wear it.

Then the 21st day of the first month is the "Ground Penetration Festival", which is also commonly known as the "Ground Penetration Festival". It often rains around the 21st day of the first month. At this time, the temperature rises, the snow melts and the precipitation increases. Just as the poem says, "The east wind thaws into rain, and everything on the earth returns in spring", rain indicates that crops can grow better, especially wheat, so this day is also "wheat day".

There is a folk saying, "Give it or not, it depends on the 21st day of the first month", which also shows that Mairi is very important.

It is said that if the weather is clear and windless on a wheat day, it indicates a bumper harvest of wheat; On the contrary, if it rains continuously on this day, it indicates that it is difficult for wheat to get a bumper harvest, which reflects people's good wishes for a bumper harvest and a rich life.
