The twentieth century did not leave this house untouched. In 1936 an underground air raid shelter was built on the southeast side of the building, as the Second Sino-Japanese War cast its shadow. During the Second World War itself, the mansion was fortunate: it was neither bombed nor damaged. After the war, the Nationalist government moved to Taiwan, and various agencies and units were stationed here in turn. It also served as a dormitory for the staff of National Tainan First Senior High School. In the 1970s it housed the East District Office and the Civil Defense Headquarters. In 1988 it was designated a municipal historical site, and from 2000 the Cultural Bureau of Tainan Municipal Government began a restoration project lasting 10 years. In 2015 the house reopened as the Magistrate Residence, with the 1900 Café, a knowledge salon and exhibitions. Since October 2020 it has been run as the Magistrate Residence Living Center, with exhibitions, lectures, household items, afternoon tea, meals and drinks. Inside, a Children's Study invites young readers into the historic house, while the first floor offers cultural and design products.
