Quack early, the wind blows fiercely, croak late, and it rains heavily.

This agricultural proverb describes the law of weather change, which means: birds sing loudly and clearly in the morning, and the wind is strong; At night, birds croak and the rain will rush. This proverb reflects a simple and common phenomenon in nature: weather changes will affect the behavior of animals.

In rural life, people need to arrange farming activities according to weather changes. For example, when the wind is strong in the morning, it is suitable for farming, sowing and other jobs that need to use wind power; But it is not suitable for outdoor work at night when the birds are low and the rain falls.

In addition, this proverb also reflects people's observation and understanding of nature. In the absence of modern scientific and technological equipment, people can only speculate on weather changes by observing natural phenomena. Therefore, this proverb can also be regarded as the accumulation of traditional knowledge and experience.

In a word, this agricultural proverb is short, but it contains rich cultural connotation and practical value. It reminds us to pay attention to the changes of nature, learn to use natural forces for production and life, and also reflects the harmonious coexistence between human beings and nature.
