What poem is used to describe bidding farewell to heartache and looking forward to a better tomorrow?

By the sinking ship, Qian Fan passed by, in front of the sick tree, Wan Muchun.

"Shipwreck" and "sick tree" are used to describe difficulties and setbacks, but the poem does not reveal resentment, but shows an open-minded and cheerful attitude towards the changes of the world and the ebb and flow of the tide. It reminds people not to be intimidated by temporary difficulties, obstacles and setbacks. We should see the "Qian Fan" next to the "sunken ship" and the "Wan Muchun" in front of the "sick tree". Losses are common. The old ones don't go, and the new ones don't come. New things will definitely replace old things, and victory will always belong to the brave.
