What are the characteristics of the Millennium solar terms?

The Millennium solar terms are characterized by the gradual replacement of the summer monsoon by the winter monsoon, the frequent southward movement of cold air, the southward movement of the position where the sun directly hits the ground, the shortening of sunshine time in the northern hemisphere, the accelerated cooling rate, the gradual widening of the temperature difference between day and night and the low air humidity.

According to the standard of "average weather temperature" proposed by modern scholar Zhang Baokun, the average weather temperature is 10-22℃ in spring or autumn. According to this standard, from the beginning of the Millennium solar term, all localities began to enter autumn one after another. At this time, the temperature difference between day and night in China can reach 8℃- 16℃, so the Millennium is a solar term with a large temperature difference in a year.

In life, to prevent autumn dryness, we can eat some foods rich in vitamins appropriately, and we can also choose some Chinese medicines that disperse lung and phlegm, nourish yin and replenish qi.

Hongyan will arrive later. Red is big and goose is small. They are two different species. Hongyan flies north in February and south in August.

Second, wait for the mysterious bird to return. The mysterious bird is the swallow, which comes from the vernal equinox and is far away from the autumnal equinox. It is a bird in the north, and flying south brings vitality. Now, flying to the north, the safflower has gone halfway, the autumn wind is bleak, and Ye Fei falls all over the mountain. "Twenty-four solar terms": "The mysterious bird sees the vernal equinox (at the beginning of the vernal equinox, the mysterious bird arrives; Yan came), at this time, he moved from north to south. Yan is a southern bird, so he returns. "

A flock of birds breeds shame. This kind of "shame" and "shame" are both delicious food. "Xuanwu hides the shade of wood, and the Dan bird is still ashamed." Raising shame means that birds perceive cold air and store food for winter, such as treasure. "Yi Zhou Shu Shi Xun": "On the day of the Millennium, the geese come, the mysterious birds return on the fifth day, and the birds are ashamed on the fifth day."
