Equinox: Every year on March 20th (or 2 1), the sun shines directly on the equator, and day and night are almost equal. Overwintering crops in vast areas of China will enter the spring growth stage.

Qingming: On April 5th (or 4th) every year, the temperature rises and the weather gets warmer. Grain Rain: Around April 20th, the rainfall increased, which was beneficial to grain growth.

Long summer: "Long summer" on May 5th or 6th. Everything grows and prospers.
