Ching Siu-tung
In 1984, Tsui formed the production company Film Workshop along with his now ex-wife and occasional co-producer, Nansun Shi, making it a home base for a tirelessly prolific roster of directing and producing projects. Here, he also developed a reputation as a hands-on and even intrusive producer of other directors' work, fuelled by public breaks with major filmmakers like John Woo and King Hu. His most longstanding and fruitful collaboration has probably been with Ching Siu-tung. As action choreographer and/or director on many Film Workshop productions, Ching made a major contribution to the well-known Tsui style.
