You can't get the money from Yangchengtong. It can only be used in public transportation, subway or 7- 1 1 and other places where Yangcheng has a credit card! (PS: if someone pays for shopping, they can wait at 7- 1 1 store. You can tell him that you can swipe his card to help him pay and see if he is willing to give you cash, but I wonder if the clerk at 7- 1 1 will help you. This method is for reference only. )
