"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 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.
