阮籍
One day at the court, on being told about a son who had killed his mother, Ruan Ji said: "Ha! If he has gone so far to kill his mother, he could allow himself to kill his father too." All, who heard this, "lost their gift of talking" and demanded him to explain himself, because "the killing of father is the worst crime in the Empire, how could you say that it is possible?" Ruan Ji replied: "Animals and birds know their mother, but are unaware of the father. Killing father – is becoming like animals and birds, but those who killed their own mother – are even worse than animals." Chronicler added: "No one could object his words."
