For example, what is "competition"

It is not "saying yes means no", but "concurrence" is a concept in criminal law, which refers to the situation that an act violates multiple crimes. Let me give you an example and see if I can make it clear:

For example, the criminal law stipulates that:

1. If you kill someone, you commit homicide.

2. If you hurt someone, you commit the crime of injury.

Then someone fired a shot, and the bullet went through one person's heart and entered another person's abdomen. The first man died and the second man was seriously injured. The man's behavior violated the above two provisions of the criminal law at the same time, that is, the crime of murder and the crime of injury. This situation is called concurrency.

I don't know. Is that clear?
