I met a plainclothes man who robbed a car in Shenzhen. He misunderstood me. At this time, did I scold him for breaking the law?

If you get angry again, it's wrong for you to curse. People are already enforcing the law. If you importune and swear, he has the right to take you away. You're obstructing official business. You have to make money by being friendly when you go out. As long as you explain clearly, you make a mistake when you curse. If he takes you away, all you have to do is admit your mistake. Don't quarrel with others, or else.
