Yes, many unpaid students in ICBC and CCB can apply for credit cards now, but the credit limit is relatively low. Some credit cards can be used for more than 5-2 times a year, and the annual fee is not very high.

It is no problem to leave it for p>1.2 months. If it is not used for one year, the annual fee will be deducted.

Payroll, ID card and company certificate can be used now.
