Is it difficult to be a good person? It's not hard to do! What's the old saying?

Good people are not difficult to do.

Liu Bei of the Three Kingdoms said (Pei Songzhi's Notes on the Biography of the Three Kingdoms Shu Shu): "Don't do little evil, don't do little good".

This sentence is about being a man, as long as it is "evil", even if it is a small evil; Do it as long as it is good, even if it is small.
