Also, Xueba has already solved problems with high school mathematics knowledge in our first grade.
I remember that the monthly exam in junior high school is based on ranking. I was only a teenager then. Xueba always sits in the first seat near the door. I still remember the picture that moved me: he always finished the questions early, leisurely took out his cup to drink water and looked out the door. The sun shines on his face, which is really charming.
