委 (wēi) in this row is listed as a bound form with an uncommon pronunciation. The character is far more commonly read wěi (third tone) as in 委托 (entrust), 委员 (committee member), 委员会 (committee), and 委婉 (tactful). The reading wēi appears in the literary expression 虚与委蛇 (wēi yí) meaning 'to deal with someone perfunctorily', but this is rare. The sole existing gloss 'surname Wei' would correspond to the wěi reading, not wēi; this may be a data error. As an HSK 7 bound form, learners encounter 委 primarily as a morpheme in formal and political vocabulary.
