Please help me to see which poem this is.

1. The sunflower in Qingqing Garden is exposed to the sun. Spring fills the earth with hope, and everything presents a scene of prosperity. I am always afraid that when the cold autumn comes, the trees in Ye Er will turn yellow and the grass will wither. The river runs to the sea, and when will it return to the west? A lazy youth, a lousy age. -"Long Songs" Guo Maoqian compiled "Yuefu Poetry Collection" 2. Industry is good and diligent, barren land; What I did was thought, but it was destroyed. Tang, Han Yu's "One Solution to Learning" or take one sentence from the study, and you will understand it yourself.
