The first day from that day after beginning of winter.

The solstice in winter is the first day of counting nine.

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 started from the day when it met Ren in winter and entered the "number nine", commonly known as "cross nine". From then on, it was called "Nine" every nine days. After nine "nines", it's just 8 1 day, and then spring blossoms.

Count nine songs:

If you don't do this in 1929,

Walking on the ice in 3949,

59 and 69, looking at the willows by the river,

The river froze in' 79, and swallows flew in' 89.

99 plus 19, plowing cattle everywhere.
