Did CCB upgrade your credit card? But if it is an upgrade, there should be a text message or phone invitation in advance. Or when you go to CCB to do business, the staff invites you to apply for a card, and you agree, so you fill out the application form. There are quite a few possibilities. If the landlord has received the new card, I suggest you keep it, because generally, CCB will not charge an annual fee, in case it will be used for travel, business trip and shopping in the future, but the card can be opened during its validity period (the validity period of the card is on the front of the card, at the lower right of the card number, with four numbers, including a slash, in the form of "month/year", for example, it is written as 5/year. If the validity period expires, the card will be invalid and the bank will not renew it for you. )

or it is suggested that the landlord can call the service hotline of CCB to confirm the card handling situation ~
