Military Police 4th Corps (Old Site) Introduction
During the February 28 Incident, the 4th Constabulary Corps was responsible for pacification operations in northern Taiwan and also collaborated with other units to "clean up" areas in Keelung City. After the declaration of martial law on March 10, the 4th Constabulary Corps was tasked with clearing operations north of Hsinchu, with Brigadier General Zhang Mutaos serving as both the corps commander and the commander of the Northern Pacification Zone. The original site of the 4th Constabulary Corps was initially the Hongji Hospital established by Dr. Lin Qingyue, and was later taken over by the Governor-General of Taiwan to establish a rehabilitation center for the treatment of opium addicts and narcotic patients. After the war, the site was relocated and occupied by the 4th Military Police Corps.
