To the south of Zhaozhou city there is a stone bridge, which was constructed by Lu Ban (c.507–444 BCE), and is extremely robust, that is to say from ancient times until today is quite without later rebuilding. It happened that the prefecture had a spirit surnamed Zhang. Passing the bridge while riding on a donkey, Zhang laughed and said: “This stone of this bridge is strong and sound; if I cross can it survive without shaking?” He then mounted the bridge, and the structure swayed as if it would collapse. Lu Ban stood beneath it and steadied the structure with his hands, returning it to its former sturdiness. To this day traces of the hooves, tail and head of the donkey ridden by Zhang are visible atop the bridge, and prints of Lu Ban’s hands can be seen below. This has been passed down from ancient times, but others have not recorded it in writing, so it is set down here.
