Why did I get a credit card of CCB for the first time and give me a limit of 22,?
there's nothing wrong with that. That is, after you apply, the bank will review your income, company contribution, personal credit and comprehensive credit status according to the information you submitted. Giving you a quota of 22, means that after the bank has examined it, it thinks that you can get this quota with your financial resources, and you can spend and use it within this quota.
