One autumn rain, one cold rain and ten autumn rains are just wearing cotton.

"One autumn rain and one cold, ten autumn rains need to wear cotton" means that after the solar terms in beginning of autumn, it will be cooler every time it rains. After ten times of rain (imaginary number), we will begin to prepare to wear cotton-padded clothes to keep out the cold. The scientific basis of this proverb is that after beginning of autumn, the direct sunlight gradually moved southward, and the light and heat in the northern hemisphere decreased day by day, which is also conducive to the enhancement and southward movement of cold air. After several times, the local temperature became very low.
