Last night, I read Wang Yi's "The江湖of Disobedience", and an article titled "Sex: The Interpretation of a Dream" was particularly interesting.
It quoted Zhou Zuoren as saying that there are two ghosts in our hearts, one is the gentleman ghost, and the other is the hooligan ghost. Some even say that all men have the subconscious thought of being a rogue or a playboy. Those who do not admit it may have problems.
