The Art of Shaking Hands?

Well, shaking hands is a very simple thing to do but if you did it wrongly, it gives the wrong message to other people. It's an action to show concern, welcome.. or whatever, politely to a person that you are shaking hands with. 当你与一个人握手时,目光是注射着另一方的时候,这是很不礼貌的行为....THat's what i saw oftenly, seriously.
