The appearance of "Hongyan Biography" in the Pre-Qin and Han Dynasties. Since the Book of Songs, the "wild goose" has changed from a "companion" in people's daily life to a sentimental image in poetry, but there is no shadow of "Hongyan passing the book". There are four articles about geese in Chu Ci, and there is a sentence in Qu Yuan's Four Ren Mei: "It's hard to say because of the bird's return." Hong Xingzu pointed out: "Thinking of geese is a good way to touch the feelings of China people." Although Qu Yuan himself did not point out that this "returning bird" that conveys love is Hongyan, although this returning bird only conveys "love", it is enough to inspire future generations' thoughts, which is not far from the Biography of Hongyan.
However, Biography of Hongyan is only a glimpse of the poems in Han Dynasty. Only Cai Yan's Eighteen Beats of Hu Jia contains "Yan Nan wants to pronounce a border tone" and "Yan Bei wants to pronounce a Chinese tone".
