The Witty Sorcerer

The Witty Sorcerer, also known as Zuo ci xi cao, is a 1931 Hong Kong historical comedy-drama film, directed by Lai Pak-hoi. It was released on 14 March 1931 after Lai's other film The Pain of Separation and starred Lai himself and Xu Menghen. It is based on a story in the 14th-century historical novel Romance of the Three Kingdoms about Zuo Ci playing tricks on Cao Cao. It was one of the earliest locally filmed Hong Kong feature films to become successful on a grand scale.
