Chapter 5, Part 3A - Lieh Tzu

The two mountains T'ai-hsing and Wang-wu, which cover an area of 700 square li, and rise to an enormous altitude, originally stood in the south of the Chi district and north of Ho-yang. The Simpleton of the North Mountain, an old man of ninety, dwelt opposite these mountains, and was vexed in spirit because their northern flanks blocked the way to travelers, who had to go all the way round. So he called his family together, and broached a plan.

'Let us,' he said, 'put forth our utmost strength to clear away this obstacle, and cut right through the mountains until we come to Han-yin. What say you?'

They all assented except his wife, who made objections and said: 'My good man has not the strength to sweep away a dunghill, let alone two such mountains as T'ai-hsing and Wang-wu. Besides, where will you put all the earth and stones that you dig up?'

The others replied that they would throw them on the promontory of P'o-hai. So the old man, followed by his son and grandson, sallied forth with their pickaxes, and the three of them began hewing away at the rocks, and cutting up the soil, and carting it away in baskets to the promontory of P'o-hai. A widowed woman who lived near had a little boy who, though he was only just shedding his milk teeth, came skipping along to give them what help he could. Engrossed in their toil, they never went home except once at the turn of the season.
