Don't do it with small kindness, and don't do it with small evil.

This is what Liu Bei said in his last testament to his son Liu Chan before his death. The original sentence reads: "Don't act on the small evil, and don't act on the small good. Only virtue and virtue can serve others. "

meaning: don't do it just because it's a minor bad thing, and don't stop doing it just because it's a minor good thing.

serving people with virtue means exercising people's admiration with good virtue. Although Liu Bei has a slight deficiency in the power of the machine, he has noble moral sentiments. And used it to influence his assassin. Before he died, Liu Bei also used it to educate his son Liu Chan, that is, "Don't do it with evil small, don't do it with good small", and "Only be virtuous and serve others".
