I don't know how many grievances there are in the world. I only know that everyone is a human being. As humans, they will be greedy, make mistakes, have feelings, pursue fame and fortune, and have plots. I am the same. I am greedy for family gatherings and your tenderness and consideration. With all these, what is the world? It is just a world of a group of people who know martial arts, but it is also an ordinary world.
