Is Zhang Yi's skill of Lian Heng a great power diplomacy or a despicable skill?

Neither. This is the way to survive, no matter what big country diplomacy or dirty tricks.

Zhang Yi's people are hard to fathom. When we usually talk about Machiavelli, what we need is not how big your brain hole is and how calm you are when you fight back to the limit, but what kind of power you can really provide: contacts, military power, money and food, and even adjusting your or your men's psychological state, all of which need you to achieve through Machiavelli.

Lian Heng was a famous strategist in the Warring States Period, and had contacts with Zhang Yi in the history books before. He thinks this man is really a scholar who manages the world. Later, he discovered that Zhang Yi is also a human being, not a god, and he has to live.

There is an anecdote that Zhang Yi was beaten half to death and still asked, "Is my tongue still there?" Of course, this is just a joke, but I think everyone can see the reality.

Zhang Yi was born in Wei. As Ren Wei, she was not appreciated by Wang Wei, so she left her native land to find another way out. Going abroad is also good. With the support of my old friend Su Qin, I'm afraid I can't get a promotion and raise immediately, and I will reach the peak of my life. As a result, Su Qin hated Yi Cheung and looked down on him. When he studied under guiguzi, they became close friends. But now the feeling of wearing a pair of trousers has changed greatly, and people will change.

The etiquette system is almost on the verge of collapse. For example, Zhou gave the land in the East to a surname. He is a scholar-bureaucrat class, and I am a little lower than you. As a result, I'm here, and your surname doesn't like me. Well, I'll make a living elsewhere. Feudal conquest, a hundred schools of thought contend. Times are chaotic. In order to realize their ambitions, many people with ideas either show what they have learned or sell their abilities at a good price and look for employers everywhere.

Zhang Yi married Lian Heng. One mouth convinced the general trend of the world, but only to curry favor with, enter through the back door and bribe people. He just wants to live in this troubled times.
