Background & setting
The story is preserved in the Liezi, Tang Wen. Taihang and Wangwu mountains block the old man’s route, giving a practical problem to a tale about persistence and time. It is a philosophical fable with a supernatural resolution, not a record of an actual excavation.
The story
The old man gathers his household to dig away the mountains and carry the material to a distant sea. His wife asks practical questions; a neighbor mocks him as foolish. He answers that even when he dies, children and grandchildren will continue, while the mountains cannot grow.
A serpent-bearing spirit hears the plan and fears that the work will never stop. The supreme ruler is moved by the old man’s sincerity and orders powerful divine sons to carry the mountains away. Human commitment and divine aid, not human labor alone, produce the ending in this version.
How to read it
The fable changes the unit of achievement from one person’s life to generations. Its practical objections also make the debate part of the story.
