Where did Su Shi draw lessons from this sentence, that is, "Return to Xi to paddle, blow away the sky, look back at the sky and look at the beautiful sky", and I want to explain it in detail.

The "Song of Bound String" in Su Shi's "Poem on a Thousand Red Cliffs" is: "Return to Xi Lan's oar, strike the sky and paint the streamer. I am pregnant, and I hope that beauty is on one side. " This song is not original by Qu Yuan, but draws on and uses many ancient works, mainly Qu Fu. Refusing to Xi Lan Paddle is from Qu Yuan's Nine Songs-Xiang Jun: "Refusing to Xi Lan Ying." "My eyes are sore and I am worried" comes from Qu Yuan's "Nine Songs-Mrs. Xiang": "My eyes are sore and I am worried". "Looking forward to the beauty and the sky" comes from Qu Yuan's Nine Songs-Less Life: "Looking forward to the beauty and the future." Among them, "looking at beauty like the sky" and using "beauty" as a metaphor for the monarch are obviously influenced by Qu Yuan's Li Sao and other articles. For example, Qu Yuan's Lisao: "I'm afraid of the beauty's death", and Nine Chapters-Thinking of Beauty: "Thinking of Beauty, I want to cry without tears." The word "beauty" in the sentence is generally considered to refer to Chu Jun (Chu Huaiwang). There is no reference to "striking the sky and tracing the streamer" in Chu Ci, but Han Yu's "Ode to Li in Chenzhou" has the following characteristics: in Cao Zhi's "Seven Wounded Poems", "the North Lake is long and bright, and the streamer is drifting away". In terms of words, it provides a reference for Fu Su.
