After searching, it is found that users of Minsheng Bank Credit Card and China Construction Bank Credit Card can participate in Mango Membership Activity 222 on Mango official website within a limited period of time, and they can redeem it directly after they are eligible. However, it should be noted that there is a time limit for this, so if it needs to be exchanged, it should be exchanged as soon as possible.

Credit card points are consumer rights rewards given by major banks in order to promote customers' consumption. Under normal circumstances, these points can only be exchanged for goods, coupons, phone bills, etc. on the apps of major banks. This is also a prize that the bank gives to customers for free.
