Is it a routine for Qingyuan Unicom business hall to handle broadband to three routers?

It may be a routine for Qingyuan Unicom business hall to handle broadband for three routers. If it's a normal route and it doesn't cost money (including various disguised charges such as deposits), don't do it for nothing. If the route is completely free but the system has been tampered with, it is recommended that you come back first and then use it for yourself (because some third-party systems can use the uploaded bandwidth or wireless network to make money for others, and some installers will use this rule to invest in a batch of routes and bind accounts with such systems themselves and then make money with customers' broadband).
