Tomorrow is the summer heat in 2022. How much do you know?
Wu Cheng, a Yuan Dynasty man, said in Summer of Twenty-four Solar Terms: "Summer is in the middle of July. Place, stop. The summer heat stops here. " It means that the solar term in summer is in the middle of July in the lunar calendar, and "Chu" means "the summer heat that stops", that is, the summer heat, which ends here.
In the midsummer solar terms, it is already the end of the "three summers", the weather changes gradually tend to be gentle, and extreme weather is no longer as active as summer. After the solar term in summer, the downward trend of temperature is further obvious.
The subtropical high will not retreat from the mainland soon after it disappears, and some places in the south will continue to be under the control of negative high. Therefore, after summer and solar terms, the temperature in some places in the south will rise, which is often called "autumn tiger". This warm weather lasts for 20 days, even for a month or two, and it is the last high temperature weather before winter.
The ancients divided the summer heat into three periods, and the so-called three periods are the changes of things. Wu Cheng, a poet in Yuan Dynasty, made a simple description of three summers in the twenty-four solar terms:
In summer, the eagle is a sacrificial bird, an eagle and a righteous bird. Autumn is golden, five acts of righteousness, and gold is cold. When the eagle senses its gas, it will catch and attack the bird. However, sacrifices must be made first, and Jews will sacrifice first. If you don't hit a bird with a fetus, that's righteousness. "
On that day in summer, the eagle sensed the cold air between heaven and earth and began to hunt birds, because the eagle belongs to the righteous bird and doesn't kill the birds that are feeding their young. Autumn belongs to gold, and it is cold. Eagles kill prey in summer and display it as sacrifices first, just like people sacrifice their ancestors before eating and drinking, so the ancients called it righteous behavior.
Five days after the summer heat, "heaven and earth began to settle down." Autumn is the beginning of gloom, so the world begins to be quiet. "The general idea is that in the second summer, the real performance is the arrival of autumn, and everything in heaven and earth begins to wither, and gradually, the weather clears up because of Su, and after cleaning up, it will bring bleak atmosphere, so the second summer is called" the beginning of Su in heaven and earth ".
The third waiting period in summer is ten days after summer. He Zhe. The total name of the cursive script jointly drafted by wo. Moreover, the genera of rice and sorghum are both grains. Get hot and climb up. "Wo" refers to millet, millet, rice and sorghum, and "Deng" means maturity. After the summer heat, the weather will get cold, and all kinds of fruits and crops will have a harvest, which is called "climbing" when it matures. As the saying goes, "summer is full of fields, and every family repairs warehouses." "So, the third stage of summer heat is He Naideng.
