張老相公，晉人。適將嫁女，攜眷至江南，躬市奩妝。舟抵金山，張先渡江，囑家人在舟，勿煿膻腥。蓋江中有黿怪，聞香輒出，壞舟吞行人，為害已久。張去，家人忘之，炙肉舟中。忽巨浪覆舟，妻女皆沒。張回棹，悼恨欲死。因登金山，謁寺僧，詢黿之異，將以仇黿。僧聞之，駭言：「吾儕日與習近，懼為禍殃，惟神明奉之，祈勿怒；時斬牲牢，投以半體，則躍吞而去。誰復能相仇哉！」張聞，頓思得計。便招鐵工，起爐山半，冶赤鐵，重百余斤。審知所常伏處，使二三健男子，以大箝舉投之，黿躍出，疾吞而下。少時，波涌如山。頃之浪息，則黿死已浮水上矣。行旅寺僧並快之，建張老相公祠，肖像其中，以為水神，禱之輒應。

Old Master Zhang was a man of Shanxi. His daughter was soon to be married, so he took his family south of the Yangtze to buy her trousseau himself. When the boat reached Mount Jin, Zhang crossed the river first, telling his household to stay on board and not to fry anything rank, meat or fish. For there was a monster turtle in the river that came up whenever it smelled cooking; it wrecked boats and swallowed travellers, and had done so for a long time. Once Zhang was gone, the household forgot, and roasted meat on the boat. Suddenly a huge wave overturned it, and his wife and daughter both drowned. Zhang rowed back, so stricken with grief and rage that he wished to die. He went up Mount Jin to see the monks of the temple and asked them about the turtle, meaning to take revenge on it. The monks were aghast. “We live beside it every day,” they said, “and for fear it will bring disaster on us we can only worship it as a god and pray it will not grow angry. From time to time we slaughter an animal and throw in half the carcass, and it leaps up, swallows it and goes away. Who could ever take revenge on it?” When Zhang heard this, a plan came to him at once. He sent for ironworkers, set up a furnace halfway up the mountain, and heated a lump of iron weighing over a hundred jin until it glowed red. Having found out where the turtle usually lay, he had two or three strong men lift the iron with great tongs and throw it in. The turtle leapt out and gulped it down. Soon the waves rose like mountains. In a moment they subsided, and the turtle was floating dead on the water. Travellers and monks alike rejoiced. They built a shrine to Old Master Zhang with his likeness inside and made him a god of the waters; whoever prays to him is answered.
