Bai Lu: "The yin qi is getting heavier, and the dew is condensed and white." As the weather gets cooler, you will find a lot of dew on the ground and leaves in the early morning, so named because of the condensation of water vapor on it at night.

The ancients used four seasons with five elements, autumn is golden, golden and white, so the autumn dew is described in white. White dew is actually a sign that the weather has turned cooler.

Generally on September 7 or 8 of the Gregorian calendar, white dews (white dews) is one of the 24 solar terms, when the temperature begins to drop, the weather turns cooler, and the grass and trees are dewed in the morning. Every year around September 7 of the Gregorian calendar, it is white dew. In ancient China, white dew was divided into three phases:

Wait for the wild goose to come; Second, the return of migratory birds; Three migratory birds are shy. It is said that this solar term is when the wild geese and swallows are waiting for the migratory birds to fly south to avoid the cold, and the birds begin to store dried fruits and grains for winter.

"White dew" is an important solar term that reflects the growth of cold in nature. Due to the cold air turning from defense to attack, the sun is still hot during the day, but the temperature drops quickly after the evening, and the temperature difference between day and night gradually widens.

When the summer monsoon is gradually replaced by the winter monsoon, the cold air turns defensive into offensive, and the direct sunlight point moves southward, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation heat dissipates quickly, so the temperature drop rate is gradually accelerating.

Bailu basically ended the sweltering heat of the summer, and the weather gradually turned cooler, and the cold dew condensed. The ancients used four seasons with five elements, autumn is golden, golden and white, and autumn dew is described in white, so it is called "white dew".

According to the standard of "waiting for the average temperature" proposed by the modern scholar Zhang Baokun, the average temperature of the weather is spring or autumn during the period of 10-22.

As the folk proverb goes, 'Expose your body in vain.' 'The weather is solemn, and you can give your ears.

It is intended to remind people that it is still hot during the day at this time, but the weather is already cool in the morning and evening, and it is easy to catch a cold if you are shirtless.

Because after the "white dew" solar term, the power of the cold air in the north continues to increase, sometimes south, resulting in the temperature gradually dropping, the temperature difference between the day and the night is increasing day and night, this kind of warm day and cool night environment is very conducive to the formation of "white dew", and is also very conducive to the transportation and accumulation of nutrients in the crop to the grain, so as to promote the rapid maturity of crops, which is a favorable condition for high yield.

Every year around September 7 of the Gregorian calendar, it is white dew. In ancient China, Bailu was divided into three phases: "one waits for the wild goose to come; Second, the return of migratory birds; Three migratory birds are shy.

It is said that this solar term is when the wild geese and swallows are waiting for the migratory birds to fly south to avoid the cold, and the birds begin to store the seepage and store dried fruits and grains for the winter. It can be seen that the white dew is actually a symbol of cooler weather.

White dew is one of the 24 solar terms, which falls between September 7 or 8 in the Gregorian calendar every year, indicating that autumn has deepened, the weather is getting cooler, and the morning dew looks refreshing and white.

2. Increased dew: The name white dew comes from the dew that appears on the ground in the morning. As autumn progresses, the temperature drops at night and the humidity of the atmosphere increases, causing the water vapor in the air to condense into a liquid and fall on the ground to form pre-dew water.

3. Harvest season: In the white dew season, the harvest season of some crops begins to arrive. When crops are ripe, such as paddy, fruits, etc., they can begin to be harvested, representing a good harvest period for agricultural production.

Closer to the autumn equinox: The Bailu solar term is the previous solar term of the autumnal equinox, which marks the equinox of day and night, the sunshine time gradually decreases, and the weather continues to get cooler. The arrival of white dew means that the autumnal equinox solar term is coming.

Overall, white dew represents the deepening of autumn and the cooler weather, marking the beginning of crop maturity and harvest season, as well as the approach of the autumnal equinox. At the same time, Bailu reminds people to pay attention to keeping warm and healthy, and adapt to the change of temperature.
