This is a poem full of philosophy, written by Hong Yingming in the Ming Dynasty.
This poem means that in the face of all kinds of honor and disgrace in life, we can be as normal as flowers bloom and fall, and we can live in peace with ourselves without interference from external evaluation or change. At the same time, I can understand that everything is a natural change, and I don't need to be too persistent or too worried, just like watching the clouds.
