第1题：

If you thought handshakes were just a gesture of greeting, then think again! A handshake is not only a way of greeting; it can also show your personality. Since we all want to set a good first impression, it is important to know the right shaking hands manners.

Stand up and maintain eye contact while shaking hands. If you are seated when someone comes for a handshake, stand up and shake his or her' hand. It is impolite to be still seated. Keep right distance between the two of you; not too close, but enough distance to shake your hands well. Keeping eye contact makes the other person feel welcome and comfortable.

Keep a handshake brief and firm. You let go of each other's hand after 2-3 seconds. Make sure your handshake ends before your conversation does. One's handshake should show a feeling of strength and warmth. The hand should be firm and not lifeless like seaweed. Then, how firm should a handshake be'? Just grasp the person's hand completely and do not press it too hard.
