you need financial proof to increase the quota. For example, I am a certificate issued by the company for a few months (it seems that the monthly income is 2, yuan, but I have been employed for a long time, but since 27, the amount of investment promotion has been 9, yuan). A copy of the property and the like can prove that as long as it can prove that you have the ability to repay, it should be said that the bank will review and increase the quota for you according to the certificate you provide. Generally, cardholder banks with good records will take the initiative to increase the fixed amount.

I hope I can help you and hope to adopt it.
