95588 can't find out when you upgrade, the customer star system will automatically evaluate, and the star refresh has a fixed cycle. Now it seems to be refreshed once a quarter, so wait patiently. No one can tell you when to upgrade this.

If it is 5 stars, it will be easy. I buy clothes and go to the supermarket to swipe my card, all of which are small, with five stars in less than half a year.

It is not so easy to rise from five stars to six stars.

Buying wealth management and spending by credit card are the fastest ways.
