"Jianjia is green and white dew
The so-called beauty is on the side of the water"
Bailu is the most poetic of the twenty-four solar terms
Why does it get its name?
"Jianjia is green, white dew is frost"
The word "Bailu" has been sung through the ages
It can be said to be the most beautiful name among all solar terms

Compared with Great Heat, Little Heat, Great Cold, and Lesser Cold
The name "Bai Lu" is very poetic
Dew is a physical phenomenon
Air The water vapor in the water condenses from gaseous state into liquid state due to temperature changes
But dewdrops do not appear only during the white dew season
There are also round dewdrops on lotus leaves in summer.
Then why is it called "white dew" at this time?
And dewdrops are obviously colorless and transparent small water drops
So where should the word "white" be? How to start?
Why did "Bailu" get its name?
This deserves our careful consideration
The double meaning of "Lu"
As the weather gradually gets cooler
At night, the water vapor in the air condenses into dewdrops
and adheres to the green stems, leaves or petals of flowers, plants and trees
The word "Lu" undoubtedly refers to crystal clear dewdrops
But this understanding is actually not comprehensive
Judging from the origin of the word "Lu"
" "Dew" consists of a prefix "rain" plus a "road"
The prefix "rain" is generally a general term for weather phenomena
Such as rain, snow, cloud (cloud), frost, fog
"路" here is first of all a phonetic symbol
But it also has its own unique meaning in word creation

The "
" in the upper right half is actually upside down "
This is the shape of a right foot
The right foot means coming means
Where are you coming?
The "mouth" on the right foot indicates a certain location
In order to express how to come to this area
When the ancients made up the Chinese character, they added a "foot" on the left side
It means walking here
So "路" was originally a verb
Refers to Walk somewhere with your feet
It can be seen from this that
In addition to expressing the meaning of dew, the "lu" in "白鹿" also means that something will happen in this season. A kind of weather phenomenon
On the occasion of white dew
Rich autumn colors appear between the sky and the earth
Migratory birds migrate, the forests are dyed, and the autumn mood is getting stronger

Various signs of autumn are beginning to appear
White dew is also white
White dew not only reveals the autumn spirit but also reveals "whiteness"
Here "Bai" does not mean white
It is related to the yin and yang and the five elements advocated by the ancients
We can understand white dew as dew white
The "white" here refers to is autumn
The ancients matched seasons, colors, directions, patron saints, etc.
one by one
Spring, summer, autumn and winter correspond to southeast, northwest
The patron saints are Qinglong, Suzaku, White Tiger and Xuanwu
The four seasons have different symbols
So "autumn" and "white" correspond to each other
Autumn and golden autumn can also be called white autumn
