Frost's Descent

The origin of the first frost is 200 words.

In ancient times, solar terms were determined by the direction of the top of the bucket handle of the Big Dipper. During the reign of Emperor Wu of the Western Han Dynasty,

The 24 Solar Terms

"Was absorbed into the taichu calendar Law, as a supplement to the calendar to guide farming. The current "twenty-four solar terms" come from the "fixed gas method" concluded more than 300 years ago (it has been used since 1645). "Constant Qi Method" is a method to determine solar terms according to the position of the sun on the ecliptic.

Every year around Gregorian calendar 10 year 10, when the sun reaches the longitude of 2 10 degrees, it is the first frost in the 24 solar terms. The first frost is the last solar term in autumn, which is the transition from autumn to winter. There is a lot of heat dissipation on the ground in autumn night, and the temperature suddenly drops below 0 degrees.

The water vapor in the air of frosted plants directly condenses on the ground or plants to form fine ice needles, and some become hexagonal frost flowers with white color and loose structure. "Twenty-four solar terms" said that the first frost: in mid-September, the gas was cold and condensed, and the dew became frost. "First frost" means that the weather is getting colder and the dew condenses into frost. In ancient China, the first frost was divided into three stages: first, the jackal sacrificed animals; Second, the vegetation is yellow; Three stings are salty. The jackal began to catch prey, sacrifice animals, and return books to heaven with animals, paving the way for sacrificing autumn gold; The leaves on the earth turned yellow and fell; The stinging insects are motionless in the cave and hang their heads into hibernation.

Legend of the first frost:

The first frost is a solar term with a fairy sister. This woman's name is Wu Jie, also called Green Girl. It is said that she is the sister of WU GANG who cut laurel trees and the goddess in charge of frost and snow.

"Huainanzi Astronomical Training" has a cloud: "In autumn and March, the ground and air do not hide, but kill, all kinds of insects crouch, live behind closed doors, and young women bring frost and snow." Gao: "Young girl, God, Young girl, master frost and snow."

On September 14 of this year, she came down to earth, stood on the highest peak in the center of Qingyao Mountain, and touched a lyre with her hand. The sound of the lyre was crisp. Frost powder and snowflakes floated down with the trembling strings and sprinkled on the earth. Frost and snow freeze and bury all impurities in the world.

Perhaps it is always accompanied by coldness, and the image of young women is full of coldness, in which melodramatic literati have played many roles. They blamed the young woman because they didn't like the loss of vegetation.

Hanshan's poem says, "When you see a withered poplar, it is often killed by a young woman". Zhang Xian's "Nanxiangzi" said, "The blood is pale and the skirt is broken. Baihui has always been jealous of Dong Jun, a frost girl. Dark fold double flowers borrow Koharu ". There is also an inexplicable name called "jealousy", as if a young woman was jealous of colorful flowers and insisted on letting the first frost fall to the ground. Yao Nai's poem: "This year, the young woman has no intention, and the yellow flower has not vomited for nine days." It's also the young woman's fault that the chrysanthemum didn't bloom. The affectionate Nalan Xingde did not let her go: "first frost news went to Yintang to make a new cool, but she was so frivolous."

Li Shangyin's poem is still the most widely circulated Frost Moon: "When you first hear the sound of wild geese, there is no cicada, and the water rises to the sky." The young woman Su E is cold-resistant, and she fights frost in the middle of the month. " I'm not afraid of anything, and the Qing girl and Chang 'e ran to the moon palace to face each other.
