If the bank calls to invite you to do it, you can just call any unit. If the bank invites you to apply for a credit card, the possibility of approval is higher, but ICBC generally has a low quota, but I suggest you apply for one first, and keep your credit record in case it is easier to apply for a credit card or loan in the future, but remember to use the credit card well, spend more and repay on time. You can earn a little money in stages, which will be good for your credit record. It will be easier to approve credit cards as a reference in the future, and it will also help your limit.
