The police made things much easier, as the assault was a fact.
The old geezer, disrespecting his age, harassed a woman and insulted people; that was also true.
In the face of such matters, it seemed the police had experience in handling them.
Moreover, the way the police spoke to Old Wang suggested that similar incidents had happened before.
"Old Wang, why do you have to do this? You've been to our place so many times, you're almost a regular visitor," the officer said.
"However, since you were hit, we've got to enforce the law impartially. Both of you, come with us to the station."
Zhang Hao explained his situation, and after considering, the police agreed.
Firstly, Zhang Hao settled his parents in a small hotel, especially since his dad was drunk.
When his dad gets drunk, sleep is his main activity, and after all, neither of his parents was involved in the brawl.
