"I'll go upstairs and check."
Ni Yang went upstairs and gently knocked on the door twice.
The child had grown up and now had her own privacy, so Ni Yang always knocked before entering her room.
Before long, the door opened.
Seeing that it was Ni Yang, Zhao Yu exclaimed joyfully, "Mom! When did you get back?"
"I just got back."
Zhao Yu grabbed Ni Yang's hand, "Come in, come in quickly."
Ni Yang followed Zhao Yu inside.
"Doggy, I heard that you've been acting a bit strange lately."
"Strange how?" Zhao Yu scratched her head.
Ni Yang glanced sideways at the books on the desk.
Zhao Yu said, "How is there anything wrong with me reading books?"
Ni Yang raised a slight eyebrow, "Have you ever seen a pig climb a tree?"
Zhao Yu shook her head, "Nope."
"Did you do something wrong?" Ni Yang continued to ask.
