I received a text message these two days. Say something about MBA. What's going on? Do any of you know? I knew it.

MBA is short for Master of Business Administration. Did you take the postgraduate entrance examination this year? If so, it is estimated that your mobile phone number was leaked after you signed up. If not, that would be strange. Maybe someone sent it by mistake. Generally, it is the enrollment newsletter of some training courses, or asking you to attend classes and then report to classes. There is an exam in January, so they rushed the students in the class before enrolling students.
