In Principal Chang's mind, he couldn't help but internally dub them as "daughter complex," not believing a word they said from the start.
It's not surprising, really; until one sees something with their own eyes, few would believe it. So, he shook his head and said, "It's getting late, you should hurry back."

It was clear to him that he didn't believe, and the Qin family didn't bother to explain anything either.
Since Zhouzhou hadn't directly stripped the spirit from him earlier, it probably wasn't an evil spirit, nothing to fear.

So, they could accept it quite readily, without preaching further. After exchanging pleasantries, they left.
