Zhoukou normal university was upgraded in 2004. I don't know what the specific professional situation is, so it's not good to comment.
In fact, the mathematics education majors in these schools, that is, mathematics and applied mathematics majors, are very close in strength.
You can compare it geographically. Luoyang's urban location, strength and environment are all good.
I recommend you to Luoyang Normal University.
PS: I'm also from the Mathematics Department of Teachers College.
