Hello, I have been engaged in gold and silver jewelry processing for more than ten years. . . Do you want to study in a private enterprise or a company? There are many companies in Fujian, where you can learn to do K-gold processing and diamond inlay. . Yu Bao. . If you want to open a processing shop, find a private school and work in the company, you'd better go to the company to study. I hope I can help you. I really didn't get a penny. . .
