Please write a proverb about the weather change.

Lei Gong sings first, it doesn't rain much.

Thunder goes round and round, but little rain falls.

It is hot in summer, but it is cool in summer.

The chimney doesn't smoke, it must be cloudy.

Fish and flowers in the river, it rains every day

Long sunny magpie noisy rain, long rainy magpie noisy sunny.
