I'm from Nanchang, Jiangxi, so your problem is easy to solve, and it's lucky. You don't need trouble. You know your card number and ask your relatives or friends to go to Bank of Communications to remit money to your card. There are two ways to know the location of your card: one is to call customer service and ask him to help you inquire, the other is to find the salesman who asked you about your card at that time, and finally it is better to ask customer service. I hope my answer is helpful to you.
