Extended data:

1, spring, summer, autumn and winter, also known as the "four seasons", is the result of the earth's orbit around the sun. 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.

2. When the earth revolves around the sun for half a week, the direct point of the sun moves from the Tropic of Cancer to the Tropic of Capricorn, and the solar heat gained by the northern hemisphere gradually decreases, from summer to autumn, and then to winter; On the other hand, the southern hemisphere goes from winter to spring, and then to summer. But the earth's orbit around the sun is not a standard perfect circle, so the summer in the southern hemisphere is slightly hotter than that in the northern hemisphere, and the winter is colder than that in the northern hemisphere.
