I also like the new guardian card, so I pay attention to it. The guardian card is a gold card. If you are a gold card user, you can call ahead to renew your card. The renewal fee is free, but you need to pay the postage in 20 yuan. If you are a Puka user, you cannot apply. You need to upgrade to a gold card first.

Other answers that it is necessary to cancel the re-application are wrong.
