Write two poems about Yueyang Tower.

Li Bai's "Ascending to the Yang Building with Twelve Summers": "The view of the building is all in Yueyang, and the cave is open."

Du Fu boarded Yueyang Tower: "I have heard about Dongting Lake for a long time, and now I finally boarded this building."

Meng Haoran's prime minister Zhang wrote in Dongting Lake: "The water in August here is in harmony with heaven. Clouds and clouds are in the valley, and Yueyang City is also trapped. "
