No evaluation is because the customer did not give the merchant an evaluation after the purchase. Now many customers are too lazy to evaluate after buying the product. Also, even if there are evaluations, many of them are not credible. Because there are too many people who are trying to gain credibility, most of the evaluations are fake. Alibaba is a wholesale mall, and Taobao is a retailer. I personally think that there are too many fakes now, and many products do not match the pictures, so the quality of the goods cannot be guaranteed.
