匳底（力鹽反蒼頡篇器物名也說文鏡匳也案奩者即香奩碁奩等是也似合底平而上有稜角經從大從品奩不成字經言奩底者取底平為喻也奩字從匚從僉僉亦聲也匚音方）。

Bottom of a casket (匳底: [匳 is] pronounced *l[i]* + *[y]an* [lián]. The *Cang Jie pian* says it is the name of a utensil. The *Shuowen [jiezi]* says: "A mirror box." Examining *lian* (奩): these are incense caskets, weiqi piece caskets, and the like. It resembles a flat-bottomed container with edges and corners on top. In the sūtra it is written with *da* (大) and *pin* (品) as 奩, which does not form a proper character. When the sūtra speaks of "the bottom of a casket", it takes the flat bottom as a simile. The character *lian* (匳) is classified under *fang* (匚) with *qian* (僉), which is also phonetic. *Fang* (匚) is pronounced *f[ang]*).
