There are more and more knock-offs (Shanzhai 山寨 in Chinese) coming out of China, the authenticity of these products are getting better and better. Of course I’m only referring to the esthetic appearance and not the quality or workmanship. The latter is the reason why counterfeit goods are worth while business for those involved.
In most cases counterfeit sellers are trying to scam people looking to buy the real thing. In the past clothing was the most popular counterfeited products, but as more and more authentic clothing brands begin to manufacture their products in China, counterfeiters no longer have the advantage of cheaply made goods. These factories begin to produce extra pieces to sell in the gray-market or they start to sell rejected items as factory-outlet items.
