I. beginning of autumn

Among the 24 solar terms in Song Dynasty, beginning of autumn's "Autumn Dew, Autumn Cold and first frost" indicates that the hot summer is coming to an end. Since that day in beginning of autumn, the temperature has gradually dropped. When I went to Qiu Lai in summer, the sky was crisp, the moon was bright and the wind was clear. Twenty-four solar terms were formulated by ancient people according to the position change of the earth on the ecliptic (that is, the orbit of the earth around the sun), and each solar term corresponds to the climate law that the sun reaches a certain position every time it runs 15 on the ecliptic.

The earth's orbit around the sun was named "ecliptic" by the ancients, also known as "solar ecliptic". The ecliptic is divided into 24 equal parts, separated by 15, forming 24 solar terms. The 24 solar terms are actually 24 solar terms, 2 per month.

Twenty-four solar terms take the earth's revolution around the sun as a cycle, which basically summarizes the different positions of the sun on the ecliptic at different times of the year, the exact time of cold coming and summer going, the laws of natural phenomena such as rainfall and snowfall, and the time of recording some phenological phenomena in nature.

Beginning of autumn doesn't mean the hot weather is over. Beginning of autumn is still in the summer heat period, but the summer heat will not come out until the second solar term in autumn, and the weather is still very hot in early autumn. The so-called "heat is in the dog days" is also called "beginning of autumn drops later", and there is at least "falling" hot weather after beginning of autumn. According to the calculation method of "dog days", the days of "beginning of autumn" are often in the middle of dog days, that is to say, the heat is not over, and the real coolness usually comes after the Millennium solar terms.

Second, the origin of solar terms in beginning of autumn

Beginning of autumn not only indicates that hot summer is coming, but also autumn is coming. It also means that the vegetation begins to bear fruit and children, and the harvest season is here. At this time, early rice harvesting and late rice transplanting in Central China, autumn crops entered an important growth and development period. The ancients regarded beginning of autumn as an important moment at the turn of summer and autumn, and always attached great importance to this solar term.

According to records, the plane tree planted in the basin was moved into the temple by Li Qiuqiu Palace in the Song Dynasty. It's time for "beginning of autumn". Tai Shigong shouted, "Autumn is here." After the play, the phoenix tree dropped one or two leaves to express autumn.
