頑鈍（上五關反下屯頓反鈍滯性也知淳注史記頑鈍猶無廉愧也蒼頡篇鈍亦頑也聲類云不利也或作頓說文從金屯聲屯音鈍昆反）。

頑鈍 (upper character: *wu* + *guan* fanqie; lower character: *tun* + *dun* fanqie; 鈍 means of a sluggish nature. Zhi Chun's commentary to the *Shiji* says: '頑鈍 means lacking a sense of shame.' The *Cang Jie pian* says: '鈍 also means stubborn.' The *Shenglei* says: 'Not sharp, blunt; alternatively written as 頓.' The *Shuowen* says: 'Derived from 金 with 屯 as phonetic.' The pronunciation of 屯 is *dun* + *kun* fanqie).
