How to tell the emperor that there are poems of disobedient people around him

Tell the emperor that there is a poem by a disobedient person: "Pro-sages are far away from villains, so the first Han dynasty prospered, pro-villains were far away from the sages, and then the Han dynasty collapsed."

This poem means to be close to the virtuous minister and alienate the villain, which is the reason for the prosperity of the former Han Dynasty, and to be close to the villain and alienate the virtuous minister, which is the reason for the collapse of the later Han Dynasty.

This is Zhuge Liang's repeated persuasion, but Liu Chan didn't take it seriously. After Zhuge Liang's death, Shu Han declined rapidly. One of the important reasons is that Liu Chan reused villains and alienated loyal subjects.
