Only Rand Mobile Phone Maintenance Training School in Shenzhen is formal, and I studied there. I went to so many places to consult them, and they are the largest in the maintenance industry. I think it's good. The teacher is quite responsible. This is Huaqiang North. Come here to learn if you want to open a shop. They have teachers to take them to the market to learn about various market conditions. I fix the motherboard. According to friends, if you want to open a shop, you only need to buy basic maintenance equipment of about 1 0,000 yuan.
