(For the sand of red bean paste, I mainly use the sand table to prevent import, prevent leakage, and occasionally test new software, or occasionally oppress the virus. The front is mainly about safe browsing U disk, not green or sand table software. Skip it, don't want to waste your time and talk about the configuration file later, it's best to look at it, it should help a little. If you don't even want to watch it, but you still want to use the sandbox, that's fine. It's very easy for me to copy the configuration file for you. You don't have to worry about it, just use it directly)
