There is no exact information about when the custom of counting nine originated. However, it was popular at least in the Northern and Southern Dynasties.

"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, from the solstice of winter, count a "nine" every nine days until the "99" of 81 days, and the weather will warm up. In fact, it is "99-99, plowing cattle everywhere"-90 days, which is 9 days.
