During the Three Kingdoms period, one person studied Zhouyi the most. Why can you calculate the time of death of Guan Yu?

The person who calculated the death time of Guan Yu is called Yu Fan. This man is smart and talented, but a little arrogant. Yu Fan learned to read hexagrams through his own practice and experience because he often studied Zhouyi. He saw from the hexagrams that Guan Yu would be killed in two days, and the result really came true. In the Three Kingdoms period, people who had strategies generally saw through the night sky or divination, such as Zhuge Liang and Dong Fangshuo, and the current technology can't explain it clearly.

Yu Fan is a little capable, but more arrogant and self-reliant. While working under Sun Quan, Sun Quan invited a guest to dinner, thinking of taking this banquet to express his condolences to his officials. When Sun Quan came to Feather Fan with a glass in his hand, Feather Fan pretended to be drunk and ignored Sun Quan. Sun Quan was so embarrassed that he had to walk away with his glass. Sun Quangang returned to his seat, and feather fan immediately sat up and continued to drink. You said that no one was angry at this situation, and Sun Quan was not a saint. He immediately wanted to slay Yu Fan, but it was the dissuasion of the minister next to him that spared Yu Fan.

Sun Quan didn't like feather fans at all, but it didn't take long for them to turn over. Sun Quan sent Lu Meng to cross the river, so he thought about finding Yu Fan to make a divination, because others said that he was good at divination, thinking that he would rather believe in a certain period of time than trust him. Yu Fan could not refuse, holding his finger and saying, Our enemy Guan Yu will not live long. Two days later, he was beheaded . It really made him count. Two days later, Guan Yu was arrested and sent to Sun Quan, who was bent on keeping Guan Yu for himself and not killing him.

But none of the ministers around Sun Quan agreed with him. After all, Guan Yu's strength is obvious to all, and everyone can understand Sun Quan's love for talents, but Guan Yu's relative threat is also great. If you don't really surrender, you might as well kill it to solve the future trouble. Sun Quan had no choice but to kill Guan Yu. Because of this incident, Sun Quan's affection for Yu Fan also rose rapidly. It can be seen that Yu Fan is familiar with the Book of Changes, appreciates the elements of the Book of Changes, and has a good opinion on divination.
