The massive arrests (tens of thousands) after the massacre in Beijing,
China have shocked the Chinese students in the US.  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
