In which months does the rainy weather appear in China, and in which areas?

Meiyu (Huangmeitian) refers to the cloudy and rainy natural climate phenomenon in the middle and lower reaches of the Yangtze River, Taiwan Province Province, south-central Japan and south Korea every year from late June to early July. Because plum rains occurred in the mature period of plums in the south of the Yangtze River, people in China call this climate phenomenon "plum rains", and this period is also called "plum rains season". 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".
