(now part of Taichung City) within six years. It is attached to the Forest Bureau of the Council of Agriculture. Besides its headquarters in Taipei City, there are 8 squadrons in Taiwan mountain area. Its main task is to support the forest patrolmen to preserve and protect the ecology system and all historic monuments in all the forests in Taiwan. Ranks Rank insignias are worn over the right breast pocket when in uniform. The rank system of the National Police Agency is as follows: 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." To emphasize the independence of the ranks and the professions, the rank of ROC police may not perfectly match their positions in a station. In 2007, a highest rank above Police Supervisor Rank 1 is created for the highest position, Police General, who is in charge of and oversees the public safety of the entire nation.

The ROC's law enforcement system built upon the foundations laid down during the Qing Dynasty with the establishment of the Peking Public Inspection Headquarters in 1902. Following the overthrow of the Qing Dynasty and the establishment of the Republic in 1912, a National Police Department was established under the auspices of the Ministry of the Interior. This early centralized system consisted of a national headquarters in the capital, provincial police administrations for each province, police departments and bureaus at the municipal and county level respectively. This system was extended to Taiwan following its transfer to ROC control in 1947, two years after the close of hostilities in World War II, though the basic system from the Japanese era was retained. In 1972, to streamline organizational costs, the National Police Department was merged with the Taiwan Police
