In the deep, mist-shrouded antiquity of northern China, long before the borders of the modern provinces were drawn, the landscape was dominated by two colossal entities of stone and earth: the Taihang and Wangwu mountains. These peaks were not merely high; they were sovereign, occupying a footprint of seven hundred square miles and soaring thousands of feet into the domain of the clouds. The Taihang range, a jagged wall of limestone and granite, stretched across the horizon like the spine of a sleeping dragon, while Wangwu stood as a bastion of spiritual energy, its crags often hidden by the veils of the celestial heavens. For the people living in the shadow of these giants, life was a series of long, circuitous journeys. To reach the markets to the south or the fertile banks of the Yellow River, one had to traverse hundreds of miles of treacherous, winding paths that skirted the base of the mountains. The peaks acted as a barrier to trade, to travel, and to the very winds that brought rain to the northern plains.
At the northern base of these mountains lived an old man of ninety years known as Yugong, or the 'Foolish Old Man.' Despite his advanced age and the silver frost that had claimed his hair and beard, Yugong’s spirit remained as sharp as a newly forged blade. He had spent nine decades watching his neighbors struggle with the mountains, seeing the exhaustion in the eyes of the young men and the frailty of the elders who could no longer make the journey around the stone walls. One evening, as the sun dipped behind the jagged silhouette of Taihang, casting a shadow that seemed to swallow the entire village, Yugong called his family together for a council. By the light of a flickering hearth, he looked upon his sons, his grandsons, and his wife, and spoke with a voice that carried the resonance of ancient bronze. 'We have lived as prisoners of these stones for too long,' he declared. 'I propose that we unite our strength to level these two mountains. We shall dig away the earth and the rock until a path is cleared, straight and true, to the banks of the Hanyin and the waters of the south.'
His wife, a woman of practical wisdom and cautious heart, looked at him with a mixture of love and disbelief. 'My husband,' she sighed, 'you speak of moving the world itself. You are ninety years old, and your strength is like the fading light of autumn. You can barely clear the briars from our garden. How can you hope to scratch even the surface of Taihang or Wangwu? And even if your sons could move the stone, where would you put it? The debris of two mountains would fill a thousand valleys.' Yugong’s sons, however, did not share their mother’s doubt. They had grown up under the oppressive weight of the peaks and saw in their father’s eyes a vision of a future without barriers. 'We shall carry the earth and the stones to the edge of the Bohai Sea,' they answered. 'We will dump the mountains into the Great Abyss, where the waters are deep enough to swallow even the highest peak.'
With the first light of the following dawn, Yugong and his three strongest sons set out. They carried iron pickaxes, bronze shovels, and heavy wicker baskets woven from the toughest willow branches. They were joined by a young boy, the son of a widowed neighbor named Jingcheng. The boy was barely seven years old, yet he skipped along with the enthusiasm of youth, eager to help in a task that everyone else in the village deemed madness. They began their work on the lower slopes, the rhythmic 'clink-clink' of metal against stone echoing through the valleys. The labor was grueling beyond measure. Each basket of earth had to be filled by hand, hoisted onto a man’s shoulders, and carried across the vast expanse of the northern plains to the coast of the Bohai Sea. The distance was so great that a single round trip—from the mountain to the sea and back again—took the better part of a year. They worked through the searing heat of summer, when the sun turned the limestone into a kiln, and through the biting winds of winter, when the earth froze as hard as iron.
