Buyers and sellers can evaluate each other after the transaction, which can be made at any time. But the content cannot be modified after the evaluation. However, if you want to cancel the bad evaluation, you can change it into a praise in the order details. The platform has the right to delete the slang words, advertisement and other information that is contrary to the public order.
In the evaluation system, it is divided into three levels of praise (default), middle evaluation, and bad evaluation, which determins the user's praise rating.
