In fact, the word "shanzhai" has a long history. As early as 2003, when the ATI 9800 graphics card was hot, there was a fake "original ATI graphics card" produced by manual workshops, early DIY players believe that the term "copycat graphics card" is still fresh in mind, and there was a copycat street in Shenzhen. But who would have thought that three years later, other electronics could be copied?
