If the campus version of Constellation Credit Card has a quota of 0 at the time of application, it is generally because of the cardholder's economic conditions. In this regard, the cardholder can deposit money in the card first, and then use the card to spend. As long as the card is used well, ICBC is likely to increase the card quota for cardholders in the later period.
If the credit card limit of Constellation Campus Edition is not zero in operation, but is reduced to zero in the process of using the card, then if it wants to increase the credit card limit, it needs to first understand what causes the credit card limit to decrease, and then take corresponding solutions to the problem. It doesn't take much effort to handle other credit cards.
