The main reason why the goods on Taobao are much cheaper than those in our shopping mall: 1. Taobao sells fake goods without risk, CCTV2 has already reported it! 2. Many goods on Taobao are not fully marked, just to cover up the production information of the products. 3. It's rare to sell genuine products and expired products, but it's difficult to identify them, depending on luck! The diamonds on Taobao are not credible, you can brush them out by paying!
