Do you know how bags and handbags are made? The first step is to make a paper grid, that is, a board room master. They can learn it in half a year, and they are very popular in the world handbag factories such as Shiling in Guangzhou and Baigou in Henan. The boardroom master sits in the boardroom just to draw a picture conveniently, earning 3 thousand to hundreds of thousands a month.
