Leave a simple heart in the world, give the years a shallow look back, look down at the floating dust and fireworks, and savor what the years are quiet.

"Leave a simple heart in the world, give the years a shallow look back, look down on the floating dust and enjoy the quiet years" is a monologue, expressing the author's feelings after experiencing the storms in the world, and feeling that he should generously put aside his troubles, let bygones be bygones, forget grievances, adjust his mood, and face work and life in a noisy society, which is very calm and uncontested.
