China has been in cold weather since the winter of November. Astronomical experts say 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. It began on the day when Winter and Ren met and entered the "Nine Counties". From then on, it was called "Nine" every nine days. After nine "nines", it is exactly 81 days, and it is "nine out". At that time, bloom was warm in spring.
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.

Astronomical experts further said that "99 songs" set each other off and became interesting, which was widely circulated among the people in China, also known as "99 pictures". There are various forms of "99 Map", such as Nine palace map, fish map, spring pattern map and sub-map.
They are not only calendars for calculating time, but also exquisite decorations. Therefore, during the winter solstice festival, China also has the custom of pasting the "Cold Map of 1999".
As a big festival, the winter solstice is still an ancient thing. After the Revolution of 1911, the custom of the Winter Solstice Festival weakened day by day, and it was difficult to see the activities of the Winter Solstice Festival everywhere. However, from the solstice of winter, "99" still has a far-reaching influence among the people in China, which is well known to women and children and widely spread.
What is "counting nine"? It is from the solstice of winter to the next few days that the weather will change from the cold of winter to the "warm day in late spring" because the process of "counting nine" is the process in which the cold pole turns warm and the cold disappears and warms. People often refer to this 998 1 day as "nine days" and "counting nine cold days".
The first nine days of "Jiujiu" are called "Yijiu", the last nine days are called "Erjiu" and the last nine days are called "Jiujiu".
