Will China Post send the wrong message?

Wrong information will not be sent. There are generally three situations. One is that scammers pretend to be China Post to commit fraud. The second is that someone else left a wrong phone number when handling business and it happened to be your number. Third, the postal staff made a mistake and entered your phone number by mistake. In short, if you do not handle business with the postal service, this information has nothing to do with you, so ignore it.
