Calculate the season from the winter solstice to nine days. The specific calculation method is to count from the winter solstice (around February 22, 65438 in the Gregorian calendar today) (the winter solstice is called "September 9", which means nine days from the beginning of cold weather), and every nine days are called "September 9", the first nine days are called "September 19", the last nine days are called "February 29" and the last nine days are called "March 9".
And so on, until "99", when the number reaches 998 1 day (around March 12 in Gregorian calendar), it is "out of nine" (when the number of nine ends, it will be cold). At this time, winter has passed and spring has arrived.
Extended data:
Winter is the season when everything is hidden, and it is also the season of tonic. As the saying goes, "make up for a winter in three or nine days, and be disease-free in the coming year." In three or nine days, tonic should be based on warming to help the human body accumulate energy.
The so-called warm tonic refers to nourishing with warm medicine. For example, cinnamon, aconite, dried ginger and pilose antler can be stewed with meat, which can offset the coldness of nourishing yin drugs on the one hand and enhance the metabolism of human body on the other hand, greatly enhancing the therapeutic effect on debilitating diseases.
The key to health care in winter is to tonify the kidney, which is a good time. While avoiding excessive fatigue, we should pay more attention to moderation and drink less to avoid the loss of kidney essence due to excessive wine color. People who are usually afraid of cold can eat more beef and mutton, and add auxiliary ingredients such as onion, garlic, ginger and pepper to improve the warmth of meat. In addition, walnuts, black sesame seeds, oranges and other foods also have a warming effect.
At the same time, three to five days is also a good opportunity to exercise and enhance physical fitness, but we should pay attention to the way, first of all, we must do enough warm-up exercises and warm-up activities. In addition, it is not advisable to choose too strenuous exercise to avoid sports injury.
