When evaluating the credit rating of a store, Magic Mirror will comprehensively consider a number of indicators, including refund rate, complaint rate, number of penalties, etc. You can't judge the level of the magic mirror just by the rate of turning your head. Other factors, such as product quality, logistics service and consumer evaluation, will also have an impact on the credit rating of the store. A high return rate does not mean that the store will be downgraded. S 1 is the highest level of the magic mirror, which means that the store data is excellent and relatively stable.
