Among the maintenance training institutions, Huayu's strength is still good. Combining practice with theory, students can basically open stores independently when they come out. Desktop, notebook and office equipment are its strengths. It seems that a mobile phone maintenance course has been opened recently. After listening to the first issue, it was ok. There are many practical machines that students can use themselves. Learning from Huayu chip-level maintenance is a correct choice. I am a student of 12, and my major is general subjects. I feel that maintenance is still relatively easy to learn, notebooks need to learn in-depth courses, and printers are relatively easy to use. The course arrangement is relatively free, and all subjects are open in cycles, so you can learn while studying. I hope my answer is helpful to you. After all, it's more real to feel for yourself. You can try it for free, and it's not too late to pay the tuition if you can.
