Longka, the central organ, is a credit card jointly launched by CCB and the central state organs. This card should be handled by civil servants of central state organs.

This should also be a standard RMB-USD dual-currency credit card, and daily consumption can also be paid directly by credit card, which is no different from other card types. But as for whether there are other special exclusive services, you should contact the customer service of CCB to find out.
