Taobao means that if you don’t know much about it, you can easily buy things with low cost performance or poor quality. For example, the same thing may have many prices, and they may all be from the same manufacturer. The source of the goods is actually the same, but the prices are different. Also, good reviews and sales can be faked, and many of them are not real. It is easy to look good with many good reviews, but in fact it is not that good.
