"Bai Lu" is the fifteenth solar term among the twenty-four solar terms and the third solar term in autumn. The White Dew Festival usually falls between September 7 and 9 in the Gregorian calendar every year. At this time, the sun reaches 165 degrees of ecliptic longitude. However, many people should know the solar term "Bai Lu", but if you ask what it means, I believe few people can understand it clearly.
White dew is similar to rain, frost, light snow, and heavy snow. They all reflect changes in the natural climate. White dew reflects the growth of cold air in nature, and the relatively large temperature difference between morning and evening. The heat of summer is gradually ending, the weather is getting cooler, and dew is forming at night. The ancients generally used the five elements to match the four seasons. Autumn belongs to gold, and gold is white. White is used to describe autumn dew. This is the origin of "white dew". There is also a sentence in "The Book of Songs", "Jianjia is green and white dew is frost", which is also a true portrayal of "white dew". The weather gradually turns cooler after the white dew season, and the temperature difference between day and night is large. But it’s not very cold yet. The temperature is still very high at noon, but it’s cooler in the morning and evening. Therefore, everyone should pay attention to adding clothes in time to prevent catching cold.
The above is the meaning of "Bai Lu". Friends, do you understand?
Each solar term has certain foods, and Bailu is no exception. So let’s take a look next, what is suitable to eat during the white dew season? And what are the specific cuisines?
Drinking white dew tea
Everyone who likes to drink tea knows that "spring tea is bitter, summer tea is astringent, drink tea with autumn white dew". After a hot summer, the tea tree basically All are dormant. In early autumn, tea trees enter a new growth period. The tea at this time is rich in flavor, neither bitter nor astringent, mellow and long-lasting, and is deeply loved by people.
Eat sweet potatoes
Sweet potatoes are harvested in autumn and are rich in starch, protein, fiber, vitamins and other nutrients. Sweet potatoes are sweet and soft, and many people like to eat them. "Compendium of Materia Medica" records: "Sweet potato nourishes deficiency, strengthens the spleen and appetite, and strengthens kidney yin." Autumn happens to be the season for people to replenish their deficiency and strengthen their kidneys. Eating some sweet potatoes in moderation is also good for the body.

In some places in Hunan, during the white dew season, newly received glutinous rice, sorghum and other grains are used to make wine. It is moderately warm and has a slightly sweet taste. This is called "white dew rice wine" ".
