It is in the articles in the Chinese book that the spring rain is shocking, the spring water is clear, the valley is clear, the summer is full, and the summer is hot.

Spring rain, spring, clear valley, summer, summer and summer are linked together in China's book solar term song.

The original song is "Spring rain surprises spring and bright valley days, summer is full and summer is hot, autumn dew is frosty, and there is Melissa Zhou in winter." This song is compiled according to the law of names for the convenience of memory. The first four sentences are composed of one word in each solar term in sequence, which is the main body of the whole solar term song, and the last four sentences are the time laws of the 24 solar terms.

There are solar terms in the poem "Spring Rain Begins with Spring and Clear Valley Days, Summer is Full and Summer is Connected with Xia Xia": beginning of spring, Rain, Sting, Equinox, Qingming, Grain Rain, Long Summer, Xiaoman, Mangzhong, Summer Solstice, Little Summer and Big Summer.

Extended data:

Twenty-four solar term song is a poem compiled for the convenience of memorizing the twenty-four solar terms in the ancient calendar of China, and many versions are circulating. Solar terms refer to the 24 solar terms and climate. It is a calendar made in ancient China to express seasonal changes and guide farming. It is the crystallization of the long-term experience and wisdom of the ancient working people in China.

Because the lunar calendar in China is a kind of "yin and yang calendar", which is based on the movement of the sun and the moon, it can't fully reflect the solar cycle. But China is an agricultural society, and agriculture needs a strict understanding of the movement of the sun, so farming is entirely based on the sun. Therefore, the "twenty-four solar terms" that reflect the solar cycle alone are added to the calendar as the standard for determining leap months.
