2 candidate readings from Wiktionary — genuine Chaozhou colloquial form not yet confirmed by a speaker. The original set of 3 candidates (gam1, gang1, gam3) was split into two sense-specific entries for 監 since gam3 ties to a distinct 'jiàn' reading (mirror/eunuch senses); this entry covers the gam1/gang1 'jiān' reading (supervise; prison).
