If a person makes a tough threat to you and claims to kill you, you can gently respond to him: it is always human nature to be born and die, and the key lies in time. Zhuangzi said in the article "Master of Health": "Let nature take its course, and sorrow and joy cannot enter, which is called hanging the emperor." Happiness can only be achieved by forgetting life and death, so whether I die or not is not a very important issue for me, but it seems to be very important for you. I don't know why. If you have time, I'd like to sit down with you and talk about philosophy. Without knives, guns and sticks, we can also have ideological conflicts.
