What time does it start at nine o'clock?
The winter solstice solar term begins.
On the solstice of winter, it is also called "crossing nine" and "counting nine". Starting from the day of winter solstice, every nine days are counted as 19 days.

Counting nine is a solar term set by the ancients to spend the long winter.
The solar term "Count Nine" was popular in the Southern and Northern Dynasties and became one of the mainstream customs. Liang Daizong wrote in the Chronicle of Jingchu: "The winter solstice is 998 1 day, which is the end of cold." Count nine cold days, that is, from the solstice of winter, count nine every nine days until the eighty-first day, and the weather will warm up.
Nine out of nine are the coldest.
Nine out of nine and four out of nine are the coldest.

On April 9, although the temperature was lower than that on March 9, the temperature difference did not change much, and it was not as cold as it was on March 9.

Wear: Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket.
In cold winter, when people put on thick clothes, heat is mainly lost from exposed parts such as head and hands. People who don't wear hats at rest lose a lot of heat from their heads. When the ambient temperature is 15℃, the heat lost by the head accounts for 30% of the total heat dissipation of human body, 60% at 4℃ and 75% at-15℃. It can be seen that the warmth of the head is closely related to the thermal balance of the human body.
