Society Is Not a Joke

Everyone has been tricked by some seemingly good people since they first entered society, because at that time we did not understand what society was, what the world was, let alone the sinister nature of people's hearts. Many times we trust others too easily, and thus we fall into a deep hole dug by others. If you have just entered society, please remember this sentence: You must not have the intention to harm others, and you must have the intention to guard against others.
