How to read the number nine in cold weather

[Shǔ ji ǔ Hanting]

It's cold for nine days, and "Nine Days" is also called "Winter 99", which is a solar term for Han people in winter. "Nine" is counted from the annual "Winter Solstice", and every nine days is a unit. There are many customs of "counting nine", among which "Jiujiu Song" is the most extensive and has a long history. In the traditional culture of Han nationality, nine is the extreme number, which is the largest, largest and longest concept. Nine nines is eighty-one, which is the "maximum" number. Ancient Han people thought that September 8 1 day must be the spring after the winter solstice. Compared with their descendants, the working people of the ancient Han nationality, especially those in the northern region, lacked the conditions to keep warm from the cold. Winter is also 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 Han people invented the method of "counting nine" to pass the time to alleviate the psychological crisis under the threat of winter. At that time, it was a carefree state to count nine around your family.
