The 14 most commonly used are:

1. be infective: show you through your behavior

2. the starting point is high: the initial request is higher, leaving room for oneself to maneuver.

After giving in, your position must be much better than a low starting point.

3. do not waver: after a position is determined, it is clear that no compromise will be made.

4. power is limited: to participate in negotiations in good faith, when you have to finalize a rule, you need to be approved by your superiors.

5. break down: if you are negotiating with a group of opponents, try to convince one of them to accept your proposal.

This person will help you convince others.

6. break negotiations or win time: suspend negotiations within a certain period of time.

When things get better, come back and renegotiate.

This time can be very short, go out and think about it, or you can leave the city for a long time.

7. face expressionless and calm: don't use emotional words to answer your opponent.

Don't respond to the pressure of the other person. Sit there and listen. Don't have any expression on your face.

8. patience: If time is in your hands, you can extend the negotiation time and improve the odds.

The less time you have, the more pressure you will have to accept your conditions.

9. narrowing the differences: it is proposed to find a compromise point in the two positions. Generally speaking, the first person to make such a proposal loses the least in the concession process.

10. be a seasoned barrister: when opposing the proposal, you might as well say, "before we accept or reject this proposal, let's see if there are any negative effects if the other party's advice is adopted."

This can make the other side aware that his proposal can not be deliberated without directly negating the opponent's suggestion.

11. first test: before making a decision, you can indirectly communicate your intentions to your opponent through a person or a reliable channel, and test your opponent's reaction.

12. surprise: it is necessary to disrupt the opponent's psychological balance by unexpectedly changing the way of negotiation.

Never let your opponent guess your next strategy.

13. find a partner with high prestige: try to get the support of a prestigious person, who should be respected and supported by his opponent.

14. bargaining: if you negotiate with several competitors at the same time, let them know about this situation.

The negotiations between these competitors will be arranged at a relatively similar time, and let them wait for a while before the meeting, so that they can be aware that some people are competing with themselves.
