Earn 1 point for every 20 yuan or 2 US dollars.

The points rule for China Merchants Bank credit cards is that 1 point will be accumulated for every 20 yuan or 2 US dollars spent. This means that when cardholders use their credit cards to make purchases, they accumulate corresponding points based on the amount of consumption, which can be used to redeem gifts, offset cash, etc. This rule encourages cardholders to increase consumption while providing points as rewards.
