Most people in this world are suffering silently.
Some people carry a heavy burden and move forward, some have no one to support them, and some people heal on their own with each passing year.
Suffering is trivial, life is mediocre, and fate is unkind.
But there is always a little kindness, a helping hand, and a persistence.
Not grand, not public, unknown.
All living beings suffer, and the remaining warmth will heal itself.
All kinds of suffering, tenderness lasts for the whole year.
Purpose: The whole book describes the difficulties that ordinary people cannot express, the pain that no one knows, and the kindness that grits one's teeth and perseveres. Each unit is the real world, and finally it is combined into one sentence: Ordinary people have their own mountains and rivers and gentleness.
