At home at noon, didn't go out of town?

you said you didn't go to other places. I don't know where your so-called local place is, and is it near Qingdao? If it is not far from Qingdao itself, it may be a signal drift.

If your home is far away from Qingdao and you receive this message, it may be that someone else left your mobile phone number wrong when asking for help from the Qingdao citizen hotline.
