What does the autumnal equinox mean in solar terms?

The autumnal equinox is one of the 24 solar terms. The arrival of the autumnal equinox indicates that autumn is getting stronger and stronger, indicating that most parts of China have entered a cool autumn, and then the temperature gradually drops and becomes colder. The date is between September 22 and 24 of the Gregorian calendar every year.

After the autumnal equinox, the direct point of the sun continued to move from the equator to the southern hemisphere, and the days in the northern hemisphere began to shorten and the nights became longer, that is, the days in a day began to be shorter than the nights; The southern hemisphere is the opposite. Therefore, the autumnal equinox is also called the landing point.

At the autumnal equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, resulting in precipitation again and again, and the temperature drops again and again. As people often say, it's time for "an autumn rain and a cold", but the daily precipitation after the autumnal equinox will not be great.

Autumn is a relatively dry season, so we should pay special attention to prevent autumn dryness, and the most important thing is to replenish enough water. In terms of diet, it is mainly moist, and we should eat more moist foods such as sesame seeds, walnuts and glutinous rice.
