Hello, I just saw your directional help. Generally, banks send it by registered mail by default, but you can apply for ems, but you can't use SF Express. Can only use postal ems, in fact, the difference is not big, and it is not appropriate. If you want to use it, you can apply through the customer service phone, that is, use ems instead, and then the fee will be deducted from your credit card, and then you can repay it. If you don't understand anything, you can ask me, or initiate targeted help, which is more satisfactory.
