The solstice in winter is the beginning of "Jiujiu Song", which is very popular in winter. The coldest season of the year in the northern hemisphere is difficult and full of joy. Although there is no dancing in spring, no colorful summer and no harvest in autumn in winter, the flying snowflakes seem to make winter particularly touching.

Jiujiu Song is a folk proverb in China. In the traditional culture of China, nine is the extreme number, which is the largest, largest and longest concept. Nine nines is eighty-one, which is the "maximum" number. People in ancient China believed that after the solstice on September 8 1 day, spring must have arrived.
