What is "Plum Rain"?

Plum rain refers to a period of continuous rainy weather in the middle and lower reaches of the Yangtze River from mid June to early and middle July every year. At this time, the south of the Yangtze River plum is ripe, so it is also called "plum rain" or "yellow plum rain". After the end of the plum rain, the rain belt moved to North China, and the Yangtze Huaihe River Basin entered the hot and rainy weather.
Meteorologically, the time when the plum rain starts and ends is called "entering the plum" and "leaving the plum" respectively.
On average, in the middle and lower reaches of the Yangtze River in China, plum blossom enters in the middle of June and emerges in the first ten days of July every year, lasting more than 20 days.
