Q: When is March 9, 20 19? A: 20191.9-20191.07.

In our country, the winter solstice is called "over nine", also called "counting nine". From winter to the next month or so, it will enter March 9, which is the really cold season of the year. As the saying goes, "on March 9, the bricks were frozen." From the solstice of winter, every nine days count as a "nine". When the eighty-first day ends, the weather will get warmer and you can go to the fields for spring ploughing.

Why is it cold for three or nine days? From the solstice of winter, we will enter the coldest nine days of the year. Every nine days is a node, and counting nine days will end the winter. In this cold 8 1 day, it is recognized that the coldest time is Sanjiu, which is what we often say is Sanjiu cold.

The reason why people say this is mainly because when the sunshine time is the shortest from winter to morning, the heat absorbed is the least, but at this time, the heat on the ground is still in stock and the ground temperature has not reached the lowest point, so the winter solstice is not the coldest time. However, due to the winter solstice, the heat consumed by the ground is far greater than the heat absorbed, and the ground heat will gradually make ends meet and consume more and more heat. It's basically the lowest ground temperature in three or nine days. After 39 days, the sun exposure time will gradually increase, and the ground temperature will gradually increase. This is why it was cold on March 9th.

Wearing a cotton-padded hat in winter is like wearing a cotton-padded jacket in winter. When people wear 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.
