Liu Bei, Guan Yu and Zhang Fei said: Don't expect to be born on the same day in the same year; But to die on the same day in the same year! Why didn't you keep your promise at last?

1. First of all, in real history, these three people are not sworn brothers. The reflection only said that the three of them acted like brothers, so of course they would not fulfill this nonexistent promise. "Three sworn relationships in Taolin" is a plot invented by Luo Guanzhong in The Romance of Three Kingdoms. It looks good in the novel, but no matter what the novel says, it can't be invented that three people really died on the same day in the same year, otherwise the plot of Shu Han can't continue.
