I'm looking for any well-known poem that talks about the beauty or wonder of nature, the world or the universe.
The beginning of《醉翁亭记》isn't a bad place to start.
环滁皆山也。其西南诸峰,林壑尤美,望之蔚然而深秀者,琅琊也。山行六七里,渐闻水声潺潺而泻出于两峰之间者,酿泉也。峰回路转,有亭翼然临于泉上者,醉翁亭也。作亭者谁?
I just fear that the whole 醉翁 part will detract from the allure of the natural world.
Any suggestions would be helpful, certainly as I don't have much of a grasp of what or wouldn't be "well-known."
