1. Don't drive the opposite part into a corner in contention.(You'd better steer clear of it in stead of arguing.) 2. Don't show off yourself excessively. (Don't show yourself a great talent or generalism so as to embarrass the other side.) 3. Don't complain endlessly and pour your misfortune out to others.(You should have suitable listeners.) 4. Don't talk about your proud things when your friends are helpless.(When you are pleased with yourself, don't forget when you were frustrated.) 5. Don't speak to others with scolding tone.(Nobody iswilling to close with other's commands and rebukings. Don't regard yourself as infallible.) 6. Don't touch privacies easily. (Privacy is a corner that is the most sensitive, the most irritability and the easiest to be hurt in one's heart.) 7. Don't have any impolite motions while talking. (Such as shaking legs, picking nose, yawning, staring at other's eyes continuously or looking at here and there and so on.) 8. Don't just talk about what you are intrested in and snub others.(You'd better take everyone's intrest in a topic and let each of them has a chance to express their views.) 9. Don't interrupt others easily. 10. Don't talk about topics that are not understood by others.!
