Why did our ancestors pay so much attention to the relationship between weather and agricultural production?

High mountains and flat plains, even if they belong to the same area, sow the same crops, the farming time must be different. Changes in climate, seasonal solar terms, temperature, etc. directly affect farmers' spring planting and autumn harvest, food, clothing, and warmth, and agricultural production.

Different regions also have different agricultural seasons. Ancient agriculture mainly relied on the weather for harvesting, so the ancestors paid great attention to the relationship between weather and agricultural production.

For this reason, the ancestors accumulated a lot of experience and lessons based on their attention to the weather and seasons for many years, and summarized countless classic agricultural proverbs, which became an important "weather" in the production and life of the ancestors. "Forecast" has brought convenience to people's production.
