In China's procuratorate system (
人民检察院 rénmín jiǎncháyuàn),
检察员 is the standard rank-and-file prosecutor — distinct from the more senior
检察官 (jiǎnchá guān, 'procurator / public prosecutor') and
检察长 (jiǎnchá zhǎng, 'chief procurator'). Translators often render all three as 'prosecutor' in English; choose the level by context. Don't confuse with
检察官,
警察 (jǐngchá, 'police officer') or
法官 (fǎguān, 'judge').
