Loulan:
Han Shu; King Loulan was greedy for money and killed many China envoys who went to the Western Regions. Later, Fu Jiezi was sent to the Western Regions to behead King Loulan and make contributions to the country. Later, poets often used "Loulan" to refer to the enemy of the border, and "breaking (splitting) Loulan" to refer to making contributions. Such as: Wang Changling's "Joining the Army" "Qinghai Yunchang Snow Mountain is dark, and the territory looks at Yumenguan. The yellow sand wears golden armor in hundreds of battles, and the loulan is not returned. " It snows in Tianshan Mountain in May, but there are no flowers, only cold. I heard the broken willow among the seedlings, but I didn't see the spring scenery. Fight the golden drum at dawn and hold the jade saddle at night. I am willing to put my sword under my waist and cut Loulan straight. "
Throw a pen:
The Book of the Later Han Dynasty records that Ban Chao was born in poverty and made a living by copying documents for the court. He once lamented that he would follow the example of Fu Jiezi and Zhang Qian to make contributions to the border region and take the title of Marquis. Later, "throwing a pen" meant abandoning literature and joining the army. For example, Xin Qiji's "Water Tune Song Tou": If you don't learn from Ban Chao's pen, you will get a post-Wan Li and a gaunt old frontier state.
Great wall:
In the Biography of Tan Daoji in the Southern History, Tan Daoji was a general in the Southern Dynasties and the Song Dynasty, with great power and was suspected by the monarch and his subjects. Later, Song Wendi took the opportunity to kill him. Tan Daoji was furious: "It's really the Great Wall of Wan Li!" Later, the Great Wall of Wan Li was used to describe the generals guarding the border. For example, Lu You's book Anger said, "The long silence in traffic jam is the first spot in the mirror." .
Bend over:
According to the Book of Song Dynasty, the Biography of Seclusion, Tao Yuanming was the magistrate of Pengze County, but he refused to "bow down to the village children and fight for rice", abandoned his official position and retired. "Bend over" means to bend over and bow, and later it means to bend over and serve others, but poets often mean the opposite. For example, "Away" in Li Bai's Sleepwalking in Tianmuling: Oh, how can I bow and scrape to those high officials whose sincere faces will never be seen?
Bi Hua:
According to Zhuangzi's Foreign Objects, Changhong, a virtuous minister of the Zhou Dynasty, was acquitted and exiled to Shu. After he committed suicide in Shu, the local people hid his blood in a jade box. Three years later, the blood became jasper. Later, people often used "Bi Hua" to describe the honest and upright people who were wronged by a just cause.
Hongyan:
In The Biography of Han Su Wu, the Huns Khan cheated the Han ambassador, and Chen Suwu was dead, but the Han ambassador deliberately said that the Emperor Wu of Han shot down a swan flying from the north when hunting, which was written by Su Wu. Khan had to let Su Wu go. Later, it was used to refer to letters and audio information such as "Red Goose", "Wild Goose Book", "Wild Goose Feet" and "Fish Goose". For example, Yan Shu's Poor Happiness: "The small print is red, and it is said that business is mediocre. The swan goose is in the clouds and the fish is in the water. This situation is hard to send. "
Dimension element:
Gulefu's "Drinking Horses in the Great Wall Cave": "Guests come from afar, leaving me a pair of carp, asking children to cook carp, and there are books in it." Later, "geometer" was used as a synonym for letters. For example, Qin Guan's "Walking on the Sand": "It is insignificant to send plum blossoms by post and fish by foot. Chen Qiang was lucky enough to go to Chen Shan. Who did he go to Xiaoxiang for? "
Qing Luan:
According to Xian Hai Jing, every time the Queen Mother of the West travels, she sends a message of Qingluan first. Later generations used "qingluan" and "bluebird" to refer to the messenger.
For example, Li Shangyin's Untitled: "Pengshan has no paths, bluebird, and listen! -Give me what she said! ."
