During the Three Kingdoms period, since the Yellow Scarf Army had to rebel because of poverty, why did Liu Bei suppress them? Didn't you say that Liu Bei is very virtuous?
I think: (1) For the public interest, the emperor of the Han Dynasty and Liu Bei belong to the same family. If the Yellow Scarf Army wanted to overthrow the Han Dynasty, how could Liu Canbei sit idly by? It is bound to save the Han Dynasty and suppress the Yellow Scarf Army. (2) Out of selfishness, if the suppression of the Yellow Scarf Army is successful, you will certainly make contributions, and with your own surname Liu, you will certainly get the official position, so that you can develop your own power. (3) Even if Liu Bei doesn't suppress it, I'm afraid the Yellow Scarf Army will still be destroyed, because Cao Cao, Sun Jian and others are also very capable. When Liu Bei suppressed, he brought hundreds or thousands of military forces. I'm afraid not many troops can be destroyed. After all, Liu Bei did not destroy the main force of the Yellow Scarf Army.
