Why can't you touch water for thousands of years?

During the "White Dew" Festival, it is an ancient custom to avoid contact with water in all parts of the human body. Millennium is the solar term after the summer heat. Among the Millennium solar terms, autumn has a stronger significance, because the temperature is higher in the daytime, lower at night, and the temperature difference between day and night is large, which leads to more dew condensation when water vapor meets vegetation or near-earth objects at night, hence the name Millennium. "almanac" said: "the bucket refers to dew, and the yin is getting heavier and heavier, so it is called dew.

Bailuyuan is located in the early August of the lunar calendar, so people are used to calling it August Festival and Bailuyuan Festival. It is the solar term with the largest temperature difference between day and night in a year, and the general temperature difference is 10℃ to 15℃, which is also the reason for more condensation. The folk proverb says: "Eighteen pots in midsummer, the white dew is not exposed." It means that if you can take a bath with a basin of water in summer, you should wear trousers and gown in the Millennium to prevent your body from being attacked by cold. This shows that the Millennium is really autumn. In the past, people often said that "mosquitoes shut up after drinking the white dew", but in fact it just showed a trend and an ideal of people. It reflects that the temperature drops at night after the Millennium, and the temperature difference between day and night is large, which affects the hatching speed of mosquito eggs. On weekdays, mosquitoes bite people very badly. There is a saying in Shandong that "in July and August, mosquitoes bite like diamonds". But after this time, mosquitoes decreased day by day and stopped biting people.
