There are many jewelry processing factories in Shenzhen, and sometimes apprentices are recruited. You can study for a few months and then leave ... There are also many processing shops in ordinary small counties. You can give your boss hundreds of thousands of dollars as tuition and ask someone to tutor you. I used to run a gold shop. Now I work in a jewelry company in Shenzhen, inlaid with platinum and diamonds ... I can talk if I have the opportunity. Q478332694
