I have encountered a similar situation. Intentional spitting has discrimination and contempt for arrogance, which has nothing to do with academic qualifications. People who deliberately spit have an evil energy that can be felt. When you think too much about such problems, you will only hurt yourself. I believe that most spitting behaviors are intentional. Many evil people will hurt some people, most of them will hurt some people psychologically, create anxiety and disharmony, and even do unexpected things in behavior. I think spitting on purpose. This is a kind of mental crime, a kind of mental injury for no reason, which is more hidden and worse than cursing and laughing. This evil spirit is evil, and there is no evidence that it harms morality. Nothing can stop it. I hope everyone can adjust their mentality more. I don't understand whether morality needs education. Morality is a natural and beautiful spiritual law. It is said that the universe has laws divorced from time and space, and matter has spiritual laws. I have never liked being close to nature as much as I do now. She brought me great relaxation and happiness. This is the best thing that the creator of the universe gave us. Only people are the most evil and ugly baptism, and their hearts have contributed a just force to nature.
