Open a computer repair shop in the county, mainly for the safety monitoring of printers in used computers! Ask the great gods to help choose a store name! None of Baidu's can be used

It should work! But you must establish a good relationship with the seller of computer hardware! So you can get the goods at a low price, which is also the source of your profits. You can't make money just by service. It is best to assemble the machine. If your investment is small, don't bet on the goods. If you want to open a computer repair shop such as home appliance repair, forget it! There is basically no future, because the integration of computer accessories is too high. If it's broken, keep it new. If it's too old, it's better to change it to a second-hand one! My friend opened a computer repair shop and knocked on second-hand parts at the same time, but it turned yellow after 1 year!
