I didn't go to Jinan, but I received a service message from Jinan.

I sometimes get this kind of short message, and sometimes there are some phones that hang up after harassment, which are everywhere. Don't worry about that. Nowadays, there are many scammers, especially those who use text messages and phone calls, and sometimes they are cheated unconsciously, so generally those junk text messages and phone calls don't have to be ignored. The state should manage these communication security issues and improve communication laws and regulations, which is beneficial to everyone.
