When is the time for three or nine days?

"March 9th" refers to the third "nine days" after the winter solstice, that is, the 19th to 27th days after the winter solstice. "The third nine days after the winter solstice" refers to "March 99", which is also the day when March 99 and April 99 intersect, not "March 99", that is, "March 99" is nine days instead of one day. ?

There is a saying in China that "nine winters count". From the solstice of winter, "Nine" is to count the seasons. The specific calculation method starts from the winter solstice (about February 22, 65438 Gregorian calendar).

Every nine days is a "nine", the first nine days are called "nine", the last nine days are called "two nine", and so on until "nine nine". When the number reaches 998 1 day (about March 12 in Gregorian calendar), it is "nine out" (the number of nine ends and it is cold). At this time, winter has passed and spring has arrived.

As the saying goes, "practicing Sanjiu in winter" is a good opportunity to exercise and enhance physical fitness, but we must pay attention to ways and means. When the outdoor temperature is too low, the blood vessels on the body surface contract, the flow velocity slows down, the muscle viscosity increases, and the ligament elasticity and joint flexibility decrease. If you exercise a lot immediately, it is easy to cause sports injuries.

So do some warm-up activities before exercise, such as jogging, rubbing your face, flapping your whole body muscles and so on. When you are free, hold your fist in your hand, connect your chin and turn around. This can increase the flexibility of fingers, prevent frostbite and prevent colds.

"Sanjiutie" is a traditional external treatment method of traditional Chinese medicine. Like the "three-volt patch", it is to treat diseases by applying some traditional Chinese medicines with the function of warming yang.

At this time, the yang is closed and the cold is the heaviest. It is most necessary to increase yang qi and eliminate cold, phlegm, dampness and drinking in the body, so as to relieve diseases such as chronic cough and asthma, repeated colds, old cold legs, diarrhea due to deficiency cold, and cold uterus.
