"Then I'll go ask."
With a skeptical attitude, the village chief came to Su Qing's house.
Su Qing has moved into this so-called haunted house for a month or two, and nothing has happened. Gradually, everyone is no longer so afraid, and at least dares to pass by Su's door.
"Su Qing, Su Qing, is Su Qing at home?"
The village chief stood at the door and poked his head inside.
Boy, what did he see.
In the Su family's yard, there is a small blackboard covered with densely written numbers.
The Su family's children were discussing a bunch of things that he couldn't understand.
“I don’t think this is a horn.”
"No, it's an angle, but it's larger than a right angle. I think it's called an obtuse angle."

The sudden sound startled everyone in the yard.
The village chief was not panicked when he saw that he was discovered. Instead, he walked slowly to the small blackboard and said, "Qing girl, please say it again. I will write it down and tell my wife about it when I get home. It sounds quite smooth."
Su Qing was confused, but he still taught it again according to the village chief's request.
"Okay, very good. I'll go back first. You wait for news at home."
After saying that, the village chief left happily.
