As for the three people upstairs, I am a student of Mathematics Department of Inner Normal University, and I also went to Leshan Normal University on Dragon Boat Festival this year. First of all, there is no such thing as chaos. That's just a feeling left over from the past, and it's not chaotic now. Speaking of math major, the math of internal teachers is definitely better than that of Leshan. It can be seen from the annual mathematical modeling competition and college students' advanced mathematics competition that Leshan is better than the internal teachers. Come on, sister. Welcome to visit.
