China has been in cold weather for several years since the winter of November. Astronomical experts said that "the Ninth Five-Year Plan" is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River. From the day of winter solstice, we entered the "number nine", commonly known as "nine crossings" From then on, every nine days is called "Nine". After nine "nines", it happens to be 8 1 day, which is "nine crosses". 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. At that time, it was a carefree state to count nine around your family. Therefore, the custom of "counting nine" is intended to kill the dreary and cold winter and look forward to the return of spring to the earth.

The written record of the custom of "counting nine" was first seen in the Chronicle of Jingchu Times written by Liang Chaozong in the Southern and Northern Dynasties in 550 AD, with a history of 1445 years. It is recorded in the book that "the number of winter solstice days is 99,81day is the end of cold".

Working people have experienced thousands of years of struggle against the severe cold and snow, and based on their long-term practical experience, they have created many "Jiujiu Songs" that describe the changes in temperature and humidity during the Jiujiu period.
