背

2 candidate readings from Wiktionary — genuine Chaozhou colloquial form not yet confirmed by a speaker. The dossier ties buê3/bu3 to this 'back; backside' sense block, while bi3 is attested only for a separate 'to carry on the back' sense, so the three original candidates are split into two entries by sense (see the other 背 entry).
