China has been in cold weather since the winter of November. "The Ninth Five-Year Plan" is a suitable solar term in northern China, especially in the middle and lower reaches of the Yellow River. It started from the day it met Ren in winter and entered the "Nine Numbers", commonly known as "Nine Crossing". From then on, it was called "Nine" every nine days. After nine "nine", it is exactly "nine out" 8 1 day. At that time, bloom was warm in spring.

In ancient times, especially in northern China, the conditions for working people to keep warm from the cold were simpler than their descendants. Winter is regarded as a threat and punishment, which directly affects people's mood and even makes them feel that winter is inexplicably long. At that time, in order to survive the long winter, the people of China invented the method of "counting nine" to pass the time, so as to alleviate the psychological crisis under the threat of winter.
