Buying a car is considered an increase in personal financial resources. You can contact the bank to see if the limit can be increased. This method of increasing the application should be different because each bank has different regulations. The CCB credit card I use is if I apply for a new credit card and then buy a car soon, I will call their customer service number to apply for a re-examination of the limit, and then they will ask me to fax the car driving license. If the credit card has been used for a long time, you cannot apply for limit re-examination. But I can go to a CCB branch to apply for a credit card of another type and hand over my driving license, which will also re-examine my personal limit.
