1) Second-hand market for college students: There is no mature second-hand market for college students now, because the main task of college students is to study, isn't it?
2) College students' second-hand websites: It seems that 58 cities and other large-scale comprehensive integrity have also been done, but their focus is not on college students and people in the second-hand society, which is not conducive to college students' second-hand transactions. Recently, a website called "Sky Paradise" appeared in my school, which is specially aimed at college students. That's good. You can have a look.
In a word, I want to find a second-hand trading website for Zhengzhou college students. I don't want to go to a large comprehensive website, but find some websites specifically for our college students, so I can buy and sell things in many ways.
