Hongyan handed down books and allusions

During the Han Dynasty, Su Wu was sent to Xiongnu and exiled by Khan to the North Sea to herd sheep. 10 years later, when the Han Dynasty approached the Huns, Khan still refused to let Su Wu return to Han. The Han Dynasty sent messengers to ask the Huns to release Su Wu, but Huns Khan lied that Su Wu was dead.

Chang Hui, who went to Xiongnu with Su Wu, confided Su Wu's situation to Ambassador China, and gave him advice to tell Xiongnu: Emperor Xian of Han shot a wild goose in Shanglinyuan, and Su Wu's silk script was tied to its foot, which proved that he was not dead, but trapped.

In this way, Xiongnu Khan could no longer lie that Su Wu was dead and had to put him back in the Han Dynasty. Since then, the story of "Hongyan Legend" has become an eternal story. And Hongyan has become a messenger.

During the Han and Tang Dynasties, Hongyan probably never delivered letters. People still call it "Goose Messenger" and the messenger is "Goose Foot". However, at the end of the Southern Song Dynasty, that is, A.D. 1274, another Hongyan really served as the ambassador of Guo Xin in the Yuan Dynasty: Hao Jing, the envoy of the Yuan Dynasty, was forbidden to enter Zhou Zhen (now Yizheng, Jiangsu Province) in 16, and later a wild goose came, with a handwritten silk script tied to a wild goose's foot.

His book says: "The wind rises and falls, and it returns to early spring. The forest pays the bow, and the poor and tired ministers have silk books. " At the end of the poem, he wrote, "The geese were released on September 1st, the 15th year of China's reunification. Don't kill Ambassador Guo Xin. Hao is in the new building of Zhenyuan Military Camp. "

Wild geese were released in autumn, and in the spring of the following year, the fruits of silk books were won by the Northern Yuan people and presented to Yuan Shizu. Kublai Khan saw that the book had been mourning for a long time, so he decided to cut the south. Two years later, the Southern Song Dynasty perished. This "Wild Goose Foot Book" was later treasured in the Yuan Dynasty secretarial office, namely the Beijing Yuan Dynasty Royal Archives.
