The grades are mainly divided into Puka, Gold Card, Platinum Card, Diamond Card and Privileged Card. Members of each level enjoy different services and benefits, such as free cash withdrawal, foreign exchange remittance discount, VIP room use, travel courtesy and so on. The level of customers is comprehensively evaluated according to their account deposits, investment in wealth management products, loan amount, credit card repayment records and other factors. The higher the level of the customer, the more rights and interests the customer has in the bank. Zheshang Bank, in most domestic banks, has a corresponding customer grading system, through which banks can provide personalized financial services, products and preferential treatment for customers of different grades.
