Perpetual Motion, from the director Ning Ying, has caused a stir even before it opens in China’s most cosmopolitan cities this week, with critics decrying its portrayal of assertive woman who treat men as sex objects. Such a film would have been inconceivable in China only five years ago. The film, featuring four women from Beijing’s educated elite, is being seen as Sex and the City, Chinese-style. The only men are two waiters who deliver lunch at the stylish home of Niuniu, a publisher, on the lunar New Year’s Eve.
