Full text * * * four natural paragraphs.

Spring, summer, autumn and winter are Chinese words, and the pinyin ch ū nxià qi ū d ū ng refers to the four seasons of the earth in a year, which is the result of the earth's orbit around the sun. The source is The Romance of Sui and Tang Dynasties, which was won by the Chu people in the Qing Dynasty.

Spring, summer, autumn and winter, also known as the "four seasons", are the results of the earth's orbit around the sun. Spring begins with "beginning of spring" in the 24 solar terms, and summer begins with "Long Summer". Autumn begins with beginning of autumn; Winter begins in beginning of winter. It is the most accurate in the Yellow River Basin. The basic laws summarized by the working people in China are: spring birth, long summer, autumn harvest and winter storage. This is also the basic idea of the relationship between man and nature elaborated in China classics such as Huangdi Neijing.
