The fifth day of the fifth lunar month.

There is an old saying, "On May 25th, Lao Long visited his mother", which is not only a story of inheriting filial piety, but also a proverb omen, indicating the weather change.

This long-standing folk story says that in the Huanghuai Valley, some say it is Henan, some say it is Anhui, and some say it is Shandong. And there is the story of White Dragon visiting his mother.

It is said that a local girl was thirsty when she was sheltering from the rain under the eaves on a day of lightning and thunder, but who would have thought that the rain she drank actually contained dragon seeds. In this way, unconsciously, her stomach is getting bigger and bigger. It's great to find an old Chinese doctor to take her pulse. This is the pulse of happiness.

You can think about it, in the past few years, this is not bad. This pure woman, who was told what to do and laughed at, was wronged by her own autonomy without any argument. In this way, I hide at home every day. Until one day, she was born suddenly, but it was a storm, lightning and thunder. She gave birth to a little white dragon, which grows with the wind. Because the girl was scared to death, Xiao Bailong surrounded her mother and refused to leave for a long time. Her face was in tears and she was speechless.

Since then, every year on the 25th day of the fifth lunar month, Xiaobai always comes to pay homage to her mother's grave, and people affectionately call her White Dragon. Moreover, on May 25th every year, there will always be lightning and thunder storms, just as the old saying goes.

There is an old saying: "The drought will not reach May 25th."

If there is a drought in May, it will ease on May 25th. Because May 25th is Huilong Day, the mother who visited Oolong shed tears to alleviate the human drought. In fact, people summed up this proverb to express farmers' eager expectation for rain in this period; In the past, people's understanding of natural phenomena was not as profound as it is now, which often cast a mysterious color on some unexplained natural phenomena.

For example, the Dragon Rain on May 20 and the Dragon Rain on May 25 of the lunar calendar are probabilistic summaries of rainfall on specific dates, but people can't explain this probabilistic phenomenon scientifically, so they call it a myth. May 25th, at the turn of midsummer, was obviously influenced by the maritime monsoon climate. Warm and humid air flow moves northward actively, and strong convective weather such as typhoon and rainstorm often occurs.

It often rains during this time, but the probability of rain on May 25th is really high. Therefore, people often take May 25th as the boundary to express their concern about drought relief and their desire for a bumper harvest and ample food and clothing after autumn.
