The Salt Paddy Girls, a Mandarin-language color film released in 1968, was the work of renowned director Guo Nanhong, starring AI Li and Wei Su. The film's motivation may have been influenced by the wholesome and realistic film Oyster Girl produced by the Central Motion Pictures Company, which was a combination of the local scenery of Taiwan and a wholesome and positive story. Therefore, the location of Salt Lady was shot in the Anshun Salt Farm in Tainan, and the plot depicts the love of a female worker in the salt farm and the mystery of her life, which includes love entanglements as well as warmth and affection.
