When the bell rang, there was a dispute in the classroom due to crowded seats. Xiao Bai pushed my desk and I couldn't sit back. The head teacher came and I joked about "townhouses", but it was still difficult to return to my seat. After my explanation, the head teacher organized the whole class to move tables and chairs, and finally solved the problem. After that, the class atmosphere improved, and this incident became a unique campus memory for me.
