The origin of the four seasons:

When the earth rotates, the axis of the earth is not perpendicular to the orbital plane, but has an inclination of 23 degrees and 27 minutes, which makes the direct point of the sun on the earth's surface move between the Tropic of Cancer and the Tropic of Capricorn, thus forming four seasons: spring, summer, autumn and winter. The basic laws summarized by the working people in China are: spring birth, long summer, autumn harvest and winter storage.

The characteristics of the four seasons can also be seen from the ancient poems describing the four seasons.

There are no birds flying over those mountains, and there are no traces of people in those paths. A boat on the river, a fisherman wearing his webworm moth; Fishing alone is not afraid of snow and ice.
