Is it still useful to open a store repeatedly and then change the network cable computer?

No, it's too much trouble and a waste of money.

There are two points. 1. There is a certain chance that the new store that has been certified on the computer will fail, which will prompt security problems. Everyone suffers from it. ! This is not a big problem. I passed the certification as soon as I used a computer that my friend didn't register in the store. 2 。 Shops that violate the rules seriously will be recorded on the computer, and it is useless to wash the system. I cleaned the system. So you can continue to use it unless you are selling something that is genuine or not illegal. If you are still selling something easy to find, you'd better change it, because your computer system is monitored.
