Young man, Confucius thought so too! If you look at history, you will find that people in every era think that "people's hearts are not ancient", and the history we see is abridged and written by successful people, so as to educate the younger generation to set an example, so the past is too beautiful and people's hearts are not ancient. Recently, I thought of Lu Xun, and suddenly thought that we are much better now than those who watched beheading and clapping in those days. What should I say? All this depends on how you choose to look at all this, some of which you can watch and some of which you don't have to watch. A pure heart is the most difficult word.
