A movie on the mainland is causing some uncomfortable moments for men. Feng Xiaogang's latest movie Cell Phone tells the story of how a suspicious wife discovers through her husband's mobile phone records and SMS memory that the 30-something TV talk-show host is cheating on her. The lead character in Cell Phone uses a variety of tricks to conceal his infidelity, plucking out his mobile batteries to make him 'not able to be reached' and telling his wife he was in a meeting to cover his dates with other women. He also regularly deletes all his short messages and call records so his eagle-eyed wife cannot detect his love affairs. 'I used the exact same way to cheat on my wife, but she found out,' said Li Xin, 34, who has been married for 10 years. 'We burst out laughing when we watched that scene together. But I didn't like the film, I felt that it intruded on my personal space,' he said. But it seems it is not just the unfaithful that are squirming in the dark. 'The movie triggers distrust between people, not necessarily only between couples,' said Wang Sujun, a 31-year-old married for five years. 'I have never cheated on my wife but the movie still made me feel uncomfortable. Who knows how many times I might have been deceived in this way?' Lu Shaoyang, a professor at Peking University's Journalism and Communication School, said such reactions are natural. 'People who get the seven-year itch often want a bit of fresh air but can't, they're suffocated by the traditions that still shape Chinese society.' Wu Jie, a 36-year-old married man, travels widely in his work as a business development manager and knows how to handle his fleeting relationships with younger women. 'I don't want to arouse my wife's suspicion,' he said. 'So every time I arrive home at the airport, the first thing I do is delete all my short messages and call records.'
