What does chill mean?

Every year, the great cold solar term is a cold time. If it's not cold, it will happen next year.

The freezing injury of wheat is the biggest loss in agriculture when late spring cold occurs in spring. In the event of severe freezing injury, wheat will be frozen to death and frostbite by the sudden attack of late spring cold, which will seriously lead to the failure of grain harvest and grain and grass harvest.
