Sun Chuanfang
The House of the Government Affairs, also known as the House of the Government Officials and the House of Documentary Affairs, was built in 1925 by Sun Chuanfang. Originally served as the Kiangsu military governor's office, it became the office building of the Chairman and other officials of the Nationalist Government from 1928 to 1935. As Chiang Kai-shek was the chairman from 1928 to 1931, there was a room in the second floor that once served as Chiang's office.
