When does Huangmeitian mean?

People living in the middle and lower reaches of the Yangtze River often have this experience: as soon as sunny and rainy spring passes, early summer will follow, but soon, the sky will be covered with clouds, rainy and rainy, and sometimes there will be bouts of heavy rain. This is what people often say, "Meiyu" is coming.

Meiyu refers to a period of continuous rainy weather from mid-June to early summer in mid-July, and the middle and lower reaches of the Yangtze River in China refer to the range of 28-34 N east of Yichang, or the narrow area from Jianghuai Valley to southern Japan.

how did you get the name "Meiyu"? Originally, it originated from a meteorological term in China. Meiyu was often called Huang Meiyu in ancient times. As early as the Han Dynasty, there were many proverbs about Huang Meiyu. In the Jin Dynasty, there has been a record of "the rain of the summer solstice, named Huang Meiyu"; Since the Tang and Song Dynasties, there have been many interesting descriptions of Meiyu. Liu Zongyuan, a writer in the Tang Dynasty, once wrote a poem about Plum Rain: "Mei Shi welcomes the rainy season, and it's late spring when it's boundless, and I'm deeply worried about the night of the ape, and the dream is over in the morning. Sea fog even the South Pole, Jiang Yun dark Beijin, plain clothes today, not for the dust of the imperial capital ". Among them, "Mei Shi welcomes the rain" means that when plums are ripe, they are greeted with the rain at three o'clock after the summer solstice. At present, the meteorological plum rain refers to a rainy weather that transits from early summer to midsummer.

He Zhu was once known as "He Mei Zi" in the Song Dynasty. It is said that it was because he wrote such a famous sentence in the word "Jade Case": "One Sichuan tobacco, the city is full of wind, and plums are raining yellow". In the Song Dynasty, Chen Yanxiao also wrote in "Poems on Geng Xi" that "when the plum blossoms in the south of the Yangtze River ripened in May, the rain continued for ten days, which was called Huang Meiyu". In the Ming Dynasty, Xu Yingmi wrote in "Talking about Hui in Yuzhitang": "After the awn, plum blossoms will be established, and after that, plum blossoms will be broken." The "Huang Meiyu" in history usually refers to the precipitation in the "Mei" festival. People in the middle and lower reaches of the Yangtze River are used to taking the solar term of "Mangzhong" as the May Festival, which coincides with the plum ripening season, so it is also called "Huangmei".

In addition, due to the high air humidity during this period, everything is easy to get damp and mildew, so people gave Meiyu another name, called "mildew rain". Xie Zaihang's Five Miscellaneous Torches in Ming Dynasty? 6? "One day, one department" describes: "Every year in March and April in the south of the Yangtze River, there is bitter rain, and everything is moldy, which is commonly called plum rain and covered when plums are green and yellow. From Xu Huai to the north, it is often dry in spring and summer. By the turn of June and July, it is raining hard and things are moldy. " In Compendium of Materia Medica, Li Shizhen, an outstanding medical scientist in the Ming Dynasty, pointed out more clearly: "Plum rain or mildew rain, when it comes to clothes and things, all produce black mold.".

it can be seen that the appellation of "plum rain" or "mildew rain" has a long history, and it began to spread in China, dating back at least 1 years.
