Why is the winter solstice blessed?

Saying "winter blessing" means: I wish you good luck in winter.

In other words, when the solar term of the winter solstice comes, it means that the blessing is coming, and the year will soon end. I hope this year's good wishes can come true.

The solstice of winter comes quietly, the fingertips are as white as frost, and the time is safe. I hope all the good things will come as scheduled, which means I hope all the good things will come as scheduled.
