When do you mean May 9th and June 9th?

May 9 and June 9 are the fifth and sixth cycles from winter to the future. At this time, the weather has begun to get warmer, which is not too cold compared with the severe cold in December.

From: "Jiujiu Song"

Origin: Compared with their descendants, the working people in ancient China, especially those in the north, lacked the conditions of keeping warm from the cold. The cold winter is regarded as a threat and punishment. They are afraid of freezing to death in the cold, which directly affects people's mood and even feels 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.
