This entry is inconsistent: the gloss 'pawn things' and the verb usage correspond to the character 当 with the fourth tone (dàng), as in 当铺 (pawnshop). However, the pinyin given here is dāng (first tone), which is the reading for unrelated senses like 'to serve as' or 'to be equal'. The headword 当当 is also unusual — the standard form for the verb 'to pawn' is a single character: 当 (dàng). You may encounter 当当 in other contexts (e.g., onomatopoeia 'ding-dong'), but not for pawning. Use with caution.
