The change method for Guangdong 0-star customers is:

Keep the credit card usage data in good condition, fix the amount in installments, and use the card reasonably for three consecutive months. I swiped a transaction on my Guangfa card and transferred it to another province. The next day, the star rating was immediately reduced from 5 to 0. I called Guangfa to make a reasonable appeal and asked for restoration. The customer service only replied that I could swipe the card more and take a look, and then catch up with Guangfa's installment event. , 20% of the fixed limit was paid in installments, and the card was restored to 4-star rating by using the card reasonably for three consecutive months.
