Letters from the Zongheng Family:

Part 1

It is to the effect that when debating with others, you must first restrain the momentum of the other party and induce the opponent to refute in order to test the opponent's strength. Sometimes it is also possible to open up the mouth to get the other party to relax their vigilance and pour out their hearts, and sometimes they can listen to the other party's statements to test their sincerity. If you want to refute others, you must grasp the evidence, or if people don't catch the evidence, you must not leak it. To deal with opponents, sometimes it is necessary to open up, sometimes to blockade, and if you can flexibly use liberalization and blockade, you can talk endlessly and change. Only in this way can we talk about people, families, countries, and the world.

Part II

It is to the effect that when debating with others, you should use the technique of repetition. If you go back to the past, you can know the past, and if you come back, you can know the present. If you try again and again, there is no bottom line that you can't touch. Sometimes you can use rhetoric to test your opponent, if you want to hear the voice, you must be silent first, if you want to open it, you must close it first, if you want to rise, you must descend first, and if you want to take it, you must give it first.

Part III

It is to the effect that to master the trick of advancing and retreating, this trick is to grasp the monarch's hobby, as long as you grasp it, you can do whatever you want, go alone. If you can follow the monarch's mood and guide or make suggestions, you can adapt and persuade the monarch.

CHAPTER IV

It is to the effect that everything is not monolithic, but has cracks. Be able to exploit the rifts of others in the debate, and at the same time, prevent the rifts of your own side. A crack like Qiu Hao can develop into a crack as big as Mount Tai. Therefore, when the crack is small, it should be repaired, when it is large, the fracture should be cut, and when it is too big to be out of control, it should be simply broken, and the crack will be eliminated.

Chapter 5

To the effect that eloquently with others should try to hook out the other party's intentions, use the flying method to set out the other party's truth, and then clamp it with pliers so that it cannot be retracted, so that it has to be led away. In this way, it can be vertical or horizontal, south or north, east or west, and reverse or reverse.

CHAPTER VI

It is to the effect that if you want to convince others, you must first weigh the length of your own talents, compare them with their own talents, and if your own talents are not as good as others, it is impossible to defeat others.

CHAPTER VII

It is to the effect that if you want to lobby the people of the world, you must be able to speculate on the true feelings of the princes, and when people are extremely excited, they cannot hide their true feelings, and when they are extremely afraid, they cannot hide their true feelings. Only then can we effectively lobby and persuade people.

CHAPTER VIII

Something to the effect that a person who is good at Moyi is as quiet as fishing, so that the fish will automatically take the bait, and the purpose of "Mo" is to stimulate the other party and let him involuntarily get on your hook. Doing things successfully makes people unaware of it.

CHAPTER IX

It is to the effect that if you want to lobby to become the master, you must measure the power of the world, and compare the terrain, strategy, wealth, guests, time, and safety of each vassal state, and then you can lobby.

CHAPTER 10

To the effect that if you want to do great things, you must have a guide, just like a compass, and the guide of lobbying is a strategy, and you must first plan well, and then lobby according to the purpose of the plan.

Article 11

It is to the effect that lobbying must first resolve doubts, and a good way to resolve doubts is to let the other party tell the truth.

CHAPTER XII

It is to the effect that the ears should be good at hearing, the eyes should be good at seeing, and if you listen with the ears of the world, you will hear everything, if you see with the eyes of the world, you will not know anything, and if you think about the heart of the world, you will know everything.

CHAPTER XIII

The gist of it is: lobbying should rely on clever words, what to say to whom, and what methods and rhetoric should be used to say what to say. Don't be simple and straightforward, study the object of the speech, and pay attention to the skills of speaking.
