Solar terms and heavy snow steamed bread

It snows heavily in winter, covering crops with a thick layer, just like covering them with three quilts (the "three" here may also be a big number in the abstract). In this way, crops will not be afraid of being "frozen to death" and "thirsty to death", and universities will also be able to exterminate insects and reap a bumper harvest next year (putting steamed bread on your pillow to sleep is an exaggerated description of the bumper harvest-steamed bread can be used as a pillow! )

Generally speaking, the basic meaning is "snow indicates a good year"
