Cao would go on to expand into directing television and television films, co-directing the television film Absolute Emotion in 2001. His solo debut as director was 2006's Trouble Makers, a satirical black comedy about a village taking revenge on a gang of hoodlums. Due to its rough content, Trouble Makers faced a host of problems from censors and spent six years in gestation before finally being released. The film premiered at the 2006 Shanghai International Film Festival, where it was called by Variety's Derek Elley as a standout entry. In 2008, Cao followed up Trouble Makers with The Equation of Love and Death, starring Zhou Xun. The film was well received and Cao would win a best new director award at the San Sebastian International Film Festival for his efforts. Watch drama online for free.
