In 1865, Jiangsu Provincial Governor Li Hongzhang purchased the American Qiji Iron Factory in Hongkou, Shanghai, and merged the original Foreign Gun Factory into it, and equipped the factory with the machines that Rong Hong purchased from the U.S., and founded Kiangnan Arsenal in Shanghai. As the former factory premises were not suitable for the new purpose, the factory was moved to Gao Chang Miao at the south part of Shanghai in 1867 with an area of over 70 mu. The Manufactory set the Machine-making Plant, Copper Foundry, Shipyard, Gun Plant, Cannon Plant, Powder Plant, Steel-making Plant, Administrative Division, Foreign Language School and other institutions, which became the largest modern military industrial enterprise in the Qing Dynasty。These documents are actually the requisition application for land for setting up Kiangnan Arsenal in Shanghai at Gao Chang Miao at the south of Shanghai submitted by the Commissioner Ying Baoshi, the Alternate Circuit Intendant Feng Junguang and Hubei Province Alternate Circuit Intendant Shen Baojing in 1866 and the Feasibility Report of the Commissioner Ying Baoshi on the site survey of Kiangnan Arsenal in Shanghai.
