Hello! Nice to meet you! Learning computer maintenance is easy! I don't know if you want to learn chip-level maintenance or ordinary computer maintenance. Ordinary people are easy to learn. You don't need to go to those training schools. Online learning can solve this problem well, hehe, and it is free! A good website is Guo Lin Computer Hospital, the cradle of computer maintenance experts! You can go and have a look! Hehe, you can ask questions you don't understand directly, and someone will answer them for you! Ha ha!
