Introduction to the Historical Materials Exhibition of the Jiangning Chief Envoy's Office: The Historical Materials Exhibition of the Jiangning Chief Envoy's Office is located in Mingzhi Building. In front of the building there is a wooden archway "Jiangning Chief Envoy's Office". The entire exhibition hall was rebuilt using ancillary buildings, restoring the old layout of the government envoy's office. The plaque with the name of the building was inscribed by contemporary calligrapher Wang Ying (a close disciple of Mr. Lin Sanzhi).
