(1). The mournful geese. Xie Huilian of the Southern Song Dynasty wrote a poem "Returning from the Lake and Playing at the Moon in the Tower": "The Aihong calls out to Shazhu, and the mournful sound of pepper sounds." A poem by Han Yu of the Tang Dynasty "Rewarding Pei for his sixteen meritorious services, Cao saw a message on his way to the west post of the mansion": "Aihong The sound clears the ears, and the sky is high in Cebu." Sun Zhiwei of the Qing Dynasty wrote a poem about "Bozhou Piling and Touching the Eyes": "The wind is strong in the evening, and a few lines are broken by mourning."
(2). "Xiaoya·Hongyan": "The wild geese are flying, whining and wailing." "Preface" says: "'Hongyan', King Mei Xuan is also. All the people are scattered and uneasy about their residence, but they can work hard to settle down and gather them." "Later, "Aihong" was used as a metaphor for the displaced people. Hongsheng of the Qing Dynasty wrote in "The Palace of Eternal Life: Recruiting the Capital": "Floated from hundreds of houses, the mourners are full of sorrow on the road." Liu Guojun's "Miscellaneous Poems Between Xinren": "Hulu Yixiang, please don't ask, the blood of the mourners in Zhongze has not dried up."
It is a metaphor for people who are sad, suffering and displaced. Looking at its origin, the term "Aihong" comes from "Hongyan". "Poetry·Xiaoya·Hongyan" says: "The wild geese are flying, whining and wailing. The wise man Weibi said that I am tired (qú, toil)." The poem writes that envoys traveled in all directions and saw refugees gathering in the wild like wild geese. When the refugees are happy that the messenger has arrived, they all join together and express their feelings, like the cries of wild geese. Later, the words "swan geese in the wild and mourning people everywhere" were used to refer to the displacement of the people. Gong Zizhen's "Miscellaneous Poems of Jihai": "In the middle of the night, Zhen (zhěn, grief) suddenly mourns and mourns, and in the ninth month there is no clothes on the Huai River." It writes about the painful and displaced life of the people.
