The nurse looked at the young man with some difficulty. She knew who he was—a local hoodlum.
Because he often liked to cause trouble, he also often ended up in the hospital. This person had no other good qualities—their greatest pleasure was causing problems, bullying people.
Of course, he only ever provoked those who seemed weaker than him. Many in the hospital unanimously believed that this young man was somewhat mentally ill. Many who had shared a room with him had been harassed by him.
But this young man did indeed have some background, so each time, it was the others who suffered. After a few incidents, the nurses and doctors all understood that this young man's favorite game was playing the pig to eat the tiger.
Moreover, up to now, he had always played his part successfully. To put it simply, this young person had some influence but seemed afraid that the whole world wouldn't know about it, so he specifically picked on those weaker than himself to bully.
