2021 new version of the nine-nine cold relief picture

I would like to share with you a set of new 2021 nine-nine cold-relieving pictures.The Nine-Nine Cold-Resisting Chart is a Chinese folk method of calculating the dates of cold weather and the blooming of spring flowers.The ancients counted nine percent every day since the winter solstice. Every nine days is a cycle. After clocking in nine and eighty-one days, it will be the time when spring flowers bloom.There are 81 persimmons, one painted red every day starting from the winter solstice (December 21).
