鍒金（上如州反玉篇云謂令金䥫之輩柔䎡也從金柔聲傳文云以石柔金是忘語也）。

鍒金 (The upper character is pronounced with the fanqie 如州 [róu]. The Yupian says: "It means making iron and the like malleable and soft; it takes 金 as radical and 柔 as phonetic." The transmission's text says 'softening metal with stone', which is errant speech.)
