The site of the industrial and mining exhibition taken by Joseph Needham, an old photograph of Chongqing in 1944

From the end of 1938 to the end of 1941, the activities of industrial and mining enterprises in the rear area of the Anti Japanese War expanded rapidly. The National Government established a large number of industrial and mining enterprises in the southwest, northwest and other areas after the Anti Japanese War by means of sole proprietorship, joint ventures with local power groups such as Sichuan and Yunnan, and participation in investment without sponsorship. The industrial department of the National Government held a large-scale industrial and mineral products exhibition in Chongqing in February 1944. The exhibition is divided into 10 branches, including the Resource Pavilion, the Coal Pavilion, the Petroleum Pavilion, the Steel Pavilion, the Non ferrous Metal Pavilion, the Special Mineral Pavilion, the Chemical Pavilion, the Electrical Appliance Pavilion, the Power Pavilion, and the Machinery Pavilion. The exhibits are all produced by the rear industrial and mining enterprises, and the exhibition is equipped with models and diagrams

This exhibition has aroused great repercussions in Chongqing. Even Chiang Kai shek came to visit the exhibition in person and asked students in Chongqing’s universities, primary and secondary schools to visit it
