What is Bailu? When the sun reaches 165° of the ecliptic longitude, it is Bailu.

What does Bailu mean? The White Dew solar term of 2017 is coming soon. Do you know what it means? Do you know what the weather is like after the White Dew solar term? Next, let’s take a look at the meaning of the White Dew solar term.

What does Bailu mean?

1. White Dew refers to the period when the weather turns cooler and the temperature drops, the yin energy gradually becomes heavier, and the morning dew becomes increasingly thicker, condensing into a layer of white water droplets. Dew is a unique natural phenomenon after the "Bai Lu" solar term.

2. The White Dew solar term is the fifteenth solar term in the twenty-four solar terms of the lunar calendar. It is the White Dew solar term when the sun reaches 165 degrees of the ecliptic longitude around September 8 every year. The time of White Dew in 2017 is 18:38:34 on September 7, which is the seventeenth day of the seventh month in the lunar calendar of 2017.

3. In ancient my country, White Dew was divided into three stages: "The first stage is the arrival of wild geese; the second stage is the return of black birds; the third stage is the collection of birds storing food." This means that during this solar term, migratory birds such as wild geese and swallows fly south to avoid the cold, and birds begin to store dry fruits and food for the winter.

Is it still hot after Bailu?

1. Dew is the water droplets formed by condensation of water vapor on the ground or near-earth objects due to the drop in temperature. Before the White Dew Festival, people can clearly feel that the hot summer has passed and the cool autumn has arrived, which clearly reflects the seasonal change from summer to autumn.

2. After the White Dew solar term, the weather turns cooler and it is also the solar term with the largest temperature difference between day and night throughout the year. As the saying goes, "The White Dew night is cold and the day is hot" and "The White Dew and Autumnal Equinox nights are colder each night."

3. Although the temperature during the day is still around 30 degrees, it drops to around 20 degrees at night, with a temperature difference of more than 10 degrees. Yang energy reaches its peak at the summer solstice, and as everything reaches its extreme, Yin energy also rises at this time.
