The allusion most editions give is Lin Xiangru returning the jade to Zhao. Around 283 BCE the state of Zhao owned the famous He Shi jade disc, and King Zhao of Qin offered fifteen cities for it. Zhao was weaker and dared not refuse, so the minister Lin Xiangru carried the disc to Qin. When the king passed it around to his courtiers and said nothing about the cities, Lin saw the offer was empty. He took the disc back on a pretext, threatened to smash it and himself against a pillar, and quietly sent it home with a servant. The tale suits a middle stick about dreams of riches: fifteen cities were promised from far away, none were real, and the treasure was saved only by someone who saw through the promise.
