众人 (zhòng rén) is a noun meaning 'many people' or 'everyone', often used in formal or written contexts. Unlike the pronoun 大家 (dà jiā, everyday 'everyone') or 大伙儿 (dà huǒr, colloquial), 众人 emphasizes a group of people collectively and is less common in casual speech. It can also refer to 'the public' in a general sense, similar to 公众 but less institutional.
