Twenty-four solar terms handwritten newspaper

The twenty-four solar terms of the lunar calendar are supplementary calendars formulated by China to guide farming in ancient times, and they are the crystallization of the long-term experience and wisdom of the working people of the ancient Han nationality.

The 24 solar terms are: beginning of spring, Rain, Sting, Equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Xiaoxia, Daxia, beginning of autumn, Chushu, Bailu, Autumn Equinox, Cold Dew, First Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold.

As early as the Spring and Autumn Period, the ancient sages of China set four solar terms, namely midsummer, midsummer, midsummer and winter solstice, and constantly improved and perfected them. By the Qin and Han Dynasties, the 24 solar terms had been completely established.

Precautions:

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.
