At the memorial service, everyone bowed to the remains.
Tips
usage
鞠躬 is used for formal bowing: at performances, ceremonies, funerals, and formal apologies. The idiom 鞠躬尽瘁 (jūgōng jìncuì) means 'to devote oneself completely (until death),' from Zhuge Liang's famous memorial.
grammar
鞠躬 can be split: 鞠了一躬 (bowed once), 鞠了三个躬 (bowed three times). The verb-object structure allows inserting 了 and a counter.
