Ancient forecast of weather forecast

Mainly based on the principle of Yin-Yang and Five Elements, in short, people in ancient China divided everything in the world into five forms: gold, wood, water, fire and earth, plus two states of Yin and Yang (this classification is not static, but also constantly changing), and made predictions according to their own states and transformation laws.

The lunar solar terms in the calendar are the weather forecasts left by our ancestors.
