Jing Ke assassinated Qin because of the righteousness in his heart and for the perpetuation of the right path in the world. Even if he died, he would still leave a lasting legacy in history. People like Jing Ke are called assassins, while Chen Yu can only be called a killer. He will kill anyone just for two meals and clothing, so Chen Yu has long been cast aside by others even if he is alive. The most miserable life is not to be spurned by others, but to be unable to control oneself, and to be unable to control oneself. Why? Chen Yu said: "Because I am a night person and only live at night."
