Despite efforts by Dreamworks animation to ensure that Chinese culture was treated with no disrespect in Kung Fu Panda 2 , the film is already drawing condemnation on the Chinese mainland. Leading the critics is fashion designer Zhao Bandi, who sued DreamWorks Animation in 2008 for conspiring to undermine China's national treasure. In an open letter appearing in Chinese newspapers, Zhao objects to the film opening just before Children's Day on Wednesday. "Children's Day should be pure. Don't turn it into a money-making day for Hollywood," he wrote. Peking University professor Kong Qingdong charged that Chinese symbols were being exploited to promote American culture. The movie, he told Xinhua, the state news agency, "is a cultural invasion." The controversy has spread to Chinese social networks, CNN observed on Monday, with several people claiming that Zhao was using the movie to draw attention to his own panda artwork and fashions. One person remarked, "Don't use Kung Fu Panda to hype your own work. It's a good movie. If you want to boycott American culture, you should cast out McDonald's and KFC."
