Why can't my Guilin bank pay online, saying that it doesn't open fast payment? Then I received the shopping cart and paid again, which also showed that express payment was not enabled.

Of course, only when express payment is enabled can express payment be made. Actually, there is a better way. You can also directly open China UnionPay and pay with money. Another way is to open Alipay, just add this card of Guilin Bank to Alipay bank card, and at the same time, in order to ensure the safety of money, there are SMS reminders in Alipay Security Center.
