How many days passed from September 19 to March 9?
From September 19 to March 9, 27 days have passed.
The coldest time:
The coldest period in winter usually occurs after the winter solstice. After beginning of winter, it means that it has entered winter, but it doesn't mean that it has started to be cold. So the heat stored on the surface in the second half of the year still has some energy, so it is not very cold. There is a folk saying that it is "a spring in October". "Xiaoyangchun in October" refers to the sunny, warm and comfortable "Xiaoyangchun" weather during the winter. So early winter (Meng Dong) is generally not very cold, but with the passage of time, cold air frequently goes south and the temperature gradually drops. In winter, the so-called "March 9 cold" is usually not too cold before the winter solstice, but the real cold is after the winter solstice, especially on March 9 and April 9.
During the winter solstice, the daytime is the shortest, the angle of direct sunlight on the ground is the smallest, and the sunshine intensity per unit area on the ground is also the smallest, so the ground gets the least solar heat every day, and the daily heat budget deficit on the ground has not reached the maximum. On the solstice after winter, although the day is growing day by day, the growth rate is very slow. From the winter solstice to the "March 9" period, the average daily growth is only about one minute. At the same time, the angle between the direct angle of the sun and the ground is slowly increasing. The daily heat budget of the ground is still in deficit, so it continues to lose heat and the ground temperature continues to drop. The deficit of total heat balance on the ground only reaches the maximum in the season of March 9. Because the temperature is mainly affected by the ground temperature, this leads to the lowest temperature in March 9 (not the whole country, but every year, depending on the region and year). In addition, around March 9, the cold air mass in Siberia also developed to a very strong stage, and the frequent invasion of strong cold air is also one of the reasons for the low temperature.
The meaning of jingle 192939
1929 Don't do it: 1929 after the winter solstice is already very cold, and your hands will be unbearable cold outside, even frostbite, so you will involuntarily put them in your pocket, which is "Don't do it".

The river opens in July and September, and swallows come in August and September: in July and September, the ice and snow begin to melt, and the frozen river surface will slowly thaw, and you will hear the gurgling sound. When the weather gets warmer in August and September, swallows will fly back from the south to nest and start a new round of busy and endless cycle.
99 plus 19, plowing cattle everywhere: 99 is the "shock" in the 24 solar terms. When the stinger wakes up, the weather gets warmer and warmer. Most parts of China have entered the spring ploughing season, and cattle ploughing is busy everywhere, but it also indicates new hope and a new beginning.
Take stock of nine health taboos
The bath water is too hot.
Bathing with too hot water will obviously dilate the blood vessels in the skin, and a large amount of blood will flow to the whole skin, leading to heart ischemia and hypoxia. If cold air enters the room, the blood vessels will contract again, and the change of heat and cold will stimulate blood pressure and heart rate.
Climb out of bed
Winter is the high incidence period of cardiovascular and cerebrovascular diseases, and cardiovascular avoidance is the most vulnerable in the morning, and 70%-80% of cardiovascular and cerebrovascular diseases suddenly occur at this time. When I wake up, I suddenly get up, and my blood pressure can't come up at once, which is easy to have an accident.
Cover your nose and mouth with a scarf.
Scarves are not cleaned often, which will absorb a lot of dust and bacteria, and the fibers will fall off easily. Covering your nose and mouth with a scarf can easily induce respiratory diseases. In addition, the scarf is not recommended to be too long to avoid strangulation when riding.
Early morning exercise
It is cold in the early morning of winter, and the cardiovascular and cerebrovascular diseases will be obviously stimulated. In the morning, pollutants are seriously accumulated, which is not suitable for exercise. It is best to do it at three or four o'clock in the afternoon, and jogging and brisk walking are appropriate. Warm up for at least 20 minutes before exercise to avoid sweating.
