Poets often compare snow to images such as the moon, sand, elements, cranes, goose feathers, mats and palms. For example, "Snow is as dark as Hu Sha, and ice is as bright as John." Compared with flying sand, moonlight and ice are metaphorical, showing the rigor and coldness of ice and snow; "I can shine on Yinshan Mountain in the Han Dynasty and chase Hu Feng through Tieguan." (Cen Can's "Snow Song in Tianshan Mountain Send Xiao Zhi to Beijing") The poet regards snow color as the moon color of his hometown, fantasizes about the strange rise, and also reveals homesickness; "Xi sand wet Han flag, chicken fan to meet. After a long separation from Liaocheng Xianhe, the sweater should have died. " (Li He's "Mocking Snow") "Liaocheng Xianhe" uses the allusion of Liaodong people returning home after learning Taoism. Here, "Long Sha" and "Su Qin" are used to compare snow, which adds a magnificent and illusory beauty to the poem and embodies Li He's artistic characteristics. "Enjoy the spring garden and see the goose feather", "Yanshan snowflake is as big as a mat" and "snowflake is as big as a palm", and the snow is as big as goose feather, mat and palm. Although it is a grandiose pen, it does not distort the strange beauty.
