The significance of Huangmeitian in May

Intermittent rain in Mao Mao (middle and lower reaches of the Yangtze River)

In early summer, there are often long rainy days in the Jianghuai basin. At this time, the utensils are easy to be moldy, so it is called "mildew rain" or "mildew" for short; Also known as "Meiyu" or "Huang Meiyu", plums in the south of the Yangtze River are yellow and ripe. It is recorded in China's historical records. For example, The Book of Beginners quoted the compilation of Emperor Liang Yuan in the Southern Dynasties, "Plum blossoms have plum rains when they are ripe". Plum Rain by Liu Zongyuan in Tang Dynasty: "Shi Mei welcomes the rain, which is infinitely worth the late spring". It is recorded in China's almanac that there is mildew rain all day: it is called "mildew" at the beginning and "mildew" all day long. The first day after the awn is planted, it will be moldy, but it will not be moldy on the first day after the light summer. Mold always enters from June 6th to 15, and mold always leaves from July 8th to 19. There is an obvious rainy season in eastern China, with a long rainy period and relatively concentrated rainfall, which is caused by the east-west north-south displacement of the main rain belt and is a unique phenomenon of atmospheric circulation in East Asia when the season changes at the turn of spring and summer. After mid-June, the rain belt remained in the Jianghuai basin, that is, Meiyu. The time that the rain belt stays is called "Meiyu season", the day when the rainy season begins is called "entering the plum blossom", and the day when it ends is called "emerging the plum blossom".

In addition, due to the high humidity in the air during this period, everything is easy to be damp and moldy, so people gave Meiyu an individual name, called "Moldy Rain". Xie Zaihang's Five Miscellaneous Torches in Ming Dynasty? "Tianbu No.1" describes: "Every year in March and April in the south of the Yangtze River, it rains bitterly, and everything is moldy, commonly known as Meiyu, and it is covered when it is green and yellow. From Xu Huai to the north, it is often dry in spring and summer. At the turn of June and July, it rains heavily and things are moldy. " Li Shizhen, an outstanding medical scientist in Ming Dynasty, pointed out more clearly in Compendium of Materia Medica: "Plum rain or mildew rain, when it comes to clothes and things, will produce black mold." .

Samsung brandy;

Huangmeitian in May.

This couplet was written by a hotel in Shanghai in the early Republic of China. As a result, the respondent won the championship without emotion, which caused a sensation and the restaurant business was booming. In the first part, the name of "brandy" is limited to "Samsung", which seems to be a number pair, but it does not specify the different meanings of "three lights, sun, moon and stars"; The second couplet uses "May" to interpret "Huangmeitian", which is in line with the seasonal climate characteristics. Taking "May" as "Samsung" and "Brandy" as "Huangmeitian" is extremely correct in part of speech. Another beauty of this couplet is that "Huangmeitian" not only talks about the weather characteristics, but also has a southern dish name, which adds infinite flavor to this couplet. It is interesting to ponder this couplet, which is a rare wonderful couplet.
