When did mildew start?

Twenty-four solar terms refer to the period from June 6th to July 19, and mold is from June 6th to 15.

In June and July every year, the warm and humid air flow in the Pacific Ocean brought by the southeast monsoon passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea, which is a climate phenomenon of continuous rainy days.

In the rainy season, the air humidity is high and the temperature is high, so clothes are easy to get moldy, so some people call the rainy season "moldy rain". After the rainy season, the weather began to be dominated by the Pacific subtropical high and officially entered the hot summer.
