These films were rarely shown decades ago, and no cinema will show them now. If you want to write an article about Chongqing movies, you can go to Daxigou (behind Chongqing Auditorium) in Yuzhong District of Chongqing Film Company to find the old employees of the former Guotai Cinema if necessary. Guotai Cinema, formerly known as Cathay Theatre before liberation, was the largest cinema in Chongqing at that time. At that time, all the films were shown there. Some old employees are still alive, and film companies can find them. Chongqing Film Company used to have a film library, and it is estimated that these film materials also exist.
