The credit line of ICBC's credit card is 00. 1 yuan. How to improve it?
Use the card for more than three months, and repay it on time every month.
Then go to the local ICBC to apply for withdrawal. If you are an unemployed college student, you can apply to raise 500/ 1000 first. It may not work any higher! ICBC's credit limit for college students is still relatively strict.
