不肖（先妙反小爾雅云不肖不似也謂不似其先也故曰不肖謂儜惡之類也說文從肉小聲也）。

Buxiao 不肖 (s- + mew[H], [xiào]; the Xiao Erya says: “Buxiao 不肖 means not resembling; it means not resembling one's ancestors”; therefore it is called buxiao 不肖, referring to cowardly and wicked types; the Shuowen jiezi says: “It is derived from the meat radical (肉) and has xiao 小 as phonetic”).
