Hanging the Pot and Asking the Gun

Some people say: "He is a doctor." Some people say: "He is a gunman." Some people say: "He is both a doctor and a gunman." As for who he is, he himself may not understand. Even though he is a doctor with a benevolent heart, he is also a gunman who enjoys grudges. He only knows that he wants the people of the world to live and work in peace and contentment, with no more illnesses, and also wants peace in the world with no more disputes.
