Wo Jiao Wo Tong Zhuo Da Ni

The poor little top-scorer was bullied, so he transferred from a high-ranked high school to an ordinary one.

Class teacher: Zhan Ming, look at the score you got!
Zhan Ming: I'll ask my deskmate to teach me.
Former classmate: Gu Qinan, don't think we can't find you just because you transferred.
Gu Qinan: I'll get my deskmate to hit you.
