What psychic calculations were there during the Three Kingdoms period?

During the Three Kingdoms period, talented people came forth in large numbers, some of whom knew how to fight and tell fortune, while others were impressed by God's prophecy.

First, Cao Cao boiled wine on heroes

Cao Cao and Liu Bei drink together, and Cao Cao treats Liu Bei differently. You know, at that time, Liu Bei was still a runaway. The two brothers drank a lot, and Cao Cao scolded all the heroes in the world. I don't know whether to flatter Liu Bei or really have a vision, just say that Liu Bei is the only hero in the world. No one took what he said seriously, but twenty years later, Liu Bei really fought against Cao Wei for more than forty years, as Cao Cao said.

Second, Zhuge Liang is right.

After reading "Long Zhong Dui", I feel that Zhuge Liang is really a fairy. His analysis of the future situation is basically effective, and there are three pillars in the world. However, Guan Yu made a mistake on strategic issues. After the loss of Jingzhou, Shu could no longer expand its territory and failed to achieve the goal of reunifying the whole country.

Third, Cui talks about Sima Yi.

Cui Tan went to Sima Lang's home, and Sima Lang introduced his home to Cui Tan. Cui has a unique vision. He saw Sima Yi's potential at a glance and concluded that Sima Yi must be a risk-averse in the future. Unfortunately, Sima Lang didn't believe it. After all, Sima Yi wants to keep a low profile in the corner. "The Book of Jin Xuandi Ji" said that "Shen Lang disagreed". Everyone knows what happened afterwards, and Sima Lang is not so rough.
