卞和 / Bian He
卞和 / Bian He enters the wiki through 《资治通鉴·周纪》74丨还原完璧归赵真相！ as the 楚国 figure whose discovery becomes 和氏璧. The episode says he offers a jade-in-stone to successive Chu rulers, is judged a fraud twice, and loses both feet before a later ruler opens the stone and finds the jade.
The page’s role is not only biographical. Bian He is the episode’s strongest example of 识宝风险: a rare object can be real while still unreadable to ordinary appraisal, and the person insisting on its value can bear the punishment for others’ failed recognition.
