The Han Feizi says two kings cut off Bian He's feet for calling a stone jade, and the Shiji says Qin later offered 15 cities for the disc

The Han Feizi, written in the third century BC, tells this story. A man of Chu named He found an uncut stone in the mountains and presented it to King Li. The royal jade expert said it was a stone. The king took this as fraud and had He's left foot cut off. When King Li died, He presented the stone to King Wu. The expert said the same, and He lost his right foot. When King Wen took the throne, He held the stone at the foot of Mount Chu and wept for three days and nights, until he wept blood. The king sent to ask why. He said he did not grieve for his feet. He grieved that a jewel was called a stone and an honest man a liar. The king had the stone cut, found jade inside, and named it He's jade disc. The Shiji says that later, in the time of King Huiwen of Zhao, Zhao obtained the disc from Chu. King Zhaoxiang of Qin wrote offering fifteen cities for it. Zhao's envoy Lin Xiangru carried it to Qin. When he saw that Qin would not hand over the cities, he threatened to smash his head and the disc together against a pillar. He then sent a servant in coarse clothes home by a side road with the disc. Later tradition says the seal of the Qin emperors was cut from this jade. It has not been found.
