They have realized that the Chinese government has been extensively monitered telephone conversations, especially international calls and dissidents groups are spied. My friend in Beijing was arrested from the clue of a telephone conversation. The Chinese students need to learn anti-spy and anti- surveillance techniques. Do you know any equiptment that can check whether the phone lines are monitored or the rooms are bugged? Do you know any anti-spy techniques in general? They need your help. Thanks, Yuan
