What is the Bailu season? What are the three signs of Bailu?

Today is Bailu. Many people have learned about the 24 solar terms in elementary school, and even memorized them. It divides the four seasons of the year into 24 solar terms, and each stage represents a different climate, which has a certain effect on clothing, farming, and harvest. The ancients believed that Yang energy reached its peak on the "Summer Solstice", and things will turn around when they reach their extremes, and Yin energy also rises at this time. By "Bailu", the Yin energy is heavier, and the dew in the morning is thicker, condensing into a layer of white water droplets, so it is called "Bailu".

What is the Bailu season?

Bailu refers to autumn, which is one of the 24 solar terms and the third solar term in autumn. At this time, it has just turned from early autumn to late autumn. The temperature will slowly begin to drop, and the temperature difference between day and night is relatively large. Although the average temperature is around 25℃, it is best to wear a coat in the morning and evening to avoid catching a cold.

Many people have learned about the 24 solar terms or even memorized them in elementary school. It divides the four seasons of the year into 24 solar terms. Each stage represents a different climate, which plays a certain role in clothing, farming, and harvesting.

Among them, Bailu is one of the traditional solar terms. It refers to autumn, the third solar term in autumn. At this time, the weather has just entered late autumn from early autumn, and the weather begins to get cooler. Bailu describes the water droplets condensed on the ground or grass and other objects in the morning due to the lowering of the climate.

So when the White Dew comes every year, it means that the weather has gradually turned cooler. The average temperature at this time is around 25℃, but there is a big temperature difference between morning and evening. If you are not careful, you will catch a cold. It is recommended to add clothes in time in the morning and evening every day.

What are the three phases of Bailu?

The first sign is five days after Bailu, when wild geese arrive. In late autumn, wild geese migrate from north to south. The big ones are called hong, and the small ones are called yan.

Five days later, the second phase is the return of the black bird. The swallows come at the spring equinox and leave at the autumn equinox. They are northern birds, and their flight to the south brings life. Now the red flowers are half-fallen and the swallows are returning. The autumn wind is bleak, and the white dew will cover the mountains and the leaves will fall.

Another five days later is the third season, when the birds start to store food. The word “xiu” here is the same as “xiu”, which means delicious food. “Storing food” means that the birds sense the austere atmosphere and start to store food for the winter, just like storing precious food.

The Origin of Bailu

"Collected Explanations of the 72 Seasonal Changes" also says: "The eighth month...the yin energy gradually becomes heavier, and the dew condenses and turns white."

The ancients believed that Yang energy reached its peak on the "Summer Solstice", and things would turn to the opposite extreme, and Yin energy also rose at this time. By "White Dew", the Yin energy was heavier, and the dew in the morning was thicker, condensing into a layer of white water droplets, so it was called "White Dew".
