Before 1999, the lowest-grade street policemen held the rank of Police Officer II, denoted by an insignia of two stars on one horizontal bar, sometimes referred to colloquially as "一毛二" or "one dime and two cents." On 3 March 1999, an adjustment of "the table of police positions and corresponding ranks" or "各級警察機關學校警察官職務配階表", from the Ministry of Interior resulted in regular policemen or women on street holding the rank of Senior Police Officer, denoted by "three stars on one horizontal bar", nicknamed "一毛三" or "one dime and three cents."
