Who are the optimistic poets after being demoted?

Liu Yuxi: Qian Fan is on the side of the sunken ship, and Wan Muchun is in front of the sick tree.

Li Bai: Oh, how can I bow and scrape to those high officials whose sincere faces will never be seen?

Bai Juyi: grass fireflies are not fire, lotus dew is beads!

Du Fu: Alas, suddenly seeing this house, it is enough for me to freeze to death alone!

Su Shi: The Yangtze River goes around the country to know the beauty of fish, and the bamboo is connected with the mountains to feel the fragrance of bamboo shoots.
