Extended data:
Hanshu recorded the story of Su Wu, saying that Su Wu was detained by Xiongnu and herded sheep in Beihai. Later, Han Ting asked Xiongnu to return Su Wu, and Xiongnu lied that Wu was dead. The Han envoy said Khan, and the Han emperor got the goose of the Northern Song Dynasty in the forest garden. The goose was full of silk, saying that Su Wu and others were in a river, so Khan had to release Su Wu to Han.
Thus, letters became synonymous with goose feet, goose silks and goose books. For another example, Shu in Song Dynasty was good at taking ten-color notes, and there were hidden lines of flowers and trees on the notes, so he gave the letters another name: Luan Notes.
