She looked up at him and realized that after not seeing him for a few years, Song Yunzheng had grown a head taller than her.

"Song Yunzheng, are you here to see me?"

Song Yunzheng nodded and said yes, but didn't say anything else, as if he didn't know what to say.

Xiao Zhuzi hugged his thighs and said, "Brother Yunyun, can Xiao Zhuzi and I go to your house to play? I want to see airplanes."

Song Yunzheng was overjoyed, "Okay, come on over, I have other models at home, I can give you one.

Little Bamboo danced with joy, "Great!"

Seeing his brother so excited, Gu Qiu also wanted to see what the model looked like, so he followed him.

Song Yunzheng took them to his room.

Their house is larger than Gu's, with two large rooms and a large living room.

The window of Song Yunzheng's room faces the yard, with shade from trees and sunshine.

There are many books on physics on the desk.

There are several models on the shelf next to it.

It is carved from wood and painted, and several parts of the model can move.

Gu Qiu sat at his desk and took Xiao Zhuzi to get the model.

Little Bamboo sat on the ground and touched them one by one.

Brother Yunyun said he would give him one and let him choose.

He wants them all, it's so hard to choose.

Little Bamboo sat on the ground, playing while wondering which one to take away.

Song Yunzheng sat next to Gu Qiu and saw that Gu Qiu was reading a book on his bookshelf.

"You can open it and take a look."

Gu Qiu glanced at him and saw that he really didn't mind, so he took out a book, which was "Principles of Physics".

"You really like physics. I remember when you were little you often said you wanted to be a physicist."

Song Yunzheng nodded, "Yes, I like it very much, and my current goal is also to be a physicist.

After that, he asked again, "What about you? You said before that you wanted to be a teacher, what about now?"
