Everything is good, but the staff is too stubborn. My friend and I, two college students, wanted to buy student tickets. My friend didn't bring his student ID, so the staff didn't recognize it when he showed it to the China Higher Education Student Information and Career Center. I brought my student ID, and I said I was an international student, so could it be allowed? The staff wanted to see my student ID, and after looking at it, they said they couldn't understand what was written on it. Then we both bought full-price tickets. I admire them.
