What does it mean to count to nine?

The number 9 means: it means that there is still 8 1 day from the winter solstice. Also known as Winter 99, it is a folk solar term in China.

Count nine, pinyin: shǔjiǔ. From the solstice in winter, every nine days is a "nine", from one "nine" to nine "nine". March 9th to April 9th is the coldest period in a year in China, so there is a saying that it is cold on March 9th. Refers to entering the "number nine".

"Liang Chao Shu Jing Chu Chun Qiu" records: "The winter solstice is 998 1 day, which is the end of cold." Count nine cold days, that is, count nine every nine days from the winter solstice to the eighty-first day, and the weather will warm up. In fact, it is "99-99, plowing cattle everywhere"-90 days, which is 9 days.

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.
