Ebay, Amazon and bookstore

they might have contracts with the Press, so they sell their used books. There might be trouble if you sell used books at home. I never think I would go to court in China, But we should be very very carefull in USA. The Chinese guy in my school just steal email account from a Professor and get a exam sheet and send one email to a girl saying professor wants to sleep with her. they put him in prison for two years.
美国, 只许州官放火，不许百姓点灯
THANKS FOR YOUR DECUSSIONS
