Every time you successfully trade using Alipay, you can make a credit rating for the trading partner. The ratings are divided into three categories: "good rating", "neutral rating" and "bad rating". Each rating corresponds to a credit score, specifically: "good rating" adds one point, "neutral rating" does not add points, and "bad rating" deducts one point. Calculation method: In each natural month, for transactions between the same buyer and seller, the seller's store rating will only be counted for the first three times. Once the store rating is made, it cannot be modified.

Calculation period: Calculate data within the past 6 months every day.
