When does Ji 'an enter the rainy season?

In the middle and lower reaches of the Yangtze River in China, the rainy season is from late June to early July every year. At this time, the sky is overcast and the precipitation is constant. In ancient times, there was a proverb that "rain hits Huangmeitou, and there is no sun for forty-five days", which is characterized by high temperature and high humidity in rainy season. Not only that, coastal cities in South China will also be hit by typhoons, and the weather and humidity will increase, making clothes and furniture more susceptible to mildew and moisture. Plum entry: the average temperature exceeds 22℃ for five consecutive days, and it rains for four consecutive days, which is regarded as plum entry and plum exit. On the contrary, if the temperature exceeds 30℃ and it doesn't rain for five consecutive days, it means that the plum leaves. Therefore, the rainy season also depends on the weather, and there is no specific time setting.
