for those who recommend China Merchants Bank, the number of cards issued is the highest in China, and the points are permanently valid, but the points are too stingy. Best service in China, with 48-hour card loss insurance;
Traffic and points are rubbish now, but the amount has been quite high, and the card design is better (personal opinion)
Others
Minsheng, Pufa, etc. see whether it is convenient to repay.
the four major state-owned banks and CGB are not recommended.
