Don't think that anyone can make money in any industry, and don't mislead others upstairs.

I own a computer repair shop and my income is relatively objective.

I repaired a diode triode to deal with the disconnection and short circuit of a board. The cost is a few cents, and the asking price is at least three or five hundred.

I used to be an apprentice in the computer city, but to be honest, I didn't do very well, because 90% of the repair shops are board-level maintenance, and they can only disassemble the unit and install it, BGA, I/O and South Bridge, and nothing else.

Later, I went to a training school to study. My own experience shows that in order to do this, we must strive for perfection. To achieve refinement, we must learn chip-level maintenance. To learn chip-level maintenance, you must understand the circuit and be able to analyze faults. These are things that computer city will never learn. Most of the experts in computer city can't read the circuit themselves, so they can only replace the parts by experience. And most of them can only do it themselves and can't talk.

Some will talk, but they don't want to talk, for fear that you will steal his business.

I don't believe many advertisements on the Internet. After comparing many schools, I studied in Shanghai. The first time I saw their notebooks, Mr. Tang published books online and posted videos on Youku. It feels good. I passed.
