孫悟空
Zhang's activities mainly focus on promoting Sun Wukong in popular culture. Zhang expressed his concern over more contemporary Sun Wukong portrayals. While Zhang stated that he was happy to see "Journey to the West", as well as other Chinese classical novels, receiving increased attention from foreign directors, he emphasized that "such adaptation has to be based on adequate knowledge of Chinese culture" and that "the Monkey King is not King Kong". Zhang believes that Goku from "Dragon Ball" does not portray the Chinese style of Sun Wukong.
