At the end of the Yuanhe period (806-20 CE), there was a commander of Huaixi, who was sent to Bianzhou, and stopped at a courier station on the way. Late at night, when he was reaching deep sleep, he suddenly awoke to find something pressing heavily onto him. The general, well-trained and strong, leapt up in alarm and began to wrestle with it, after which the unidentified thing withdrew, and the general succeeded in wresting a leather bag from its hand. The ghost begged and implored with great bitterness from the darkness, so the commander addressed it: “If you tell me what it is, I will give it back.” The spirit said, after a long time, “This is a bag of surplus qi.” The commander then picked up a brick and struck out with it, at which the voice was silenced. The bag held several sheng (these are about a litre each), its contents were deep red in colour, and looked like lotus-root fibres; when carried in daylight it cast no shadow.
Taken from Youyang zazu.

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.
