After taking the safety engineer exam, I received many strange phone calls and text messages.

The next mobile phone housekeeper can automatically block it. Tencent mobile phone housekeeper will do, or Jinshan mobile assistant and the like have this function. In addition: it is best not to leave your real phone number, especially your mobile phone, in the vocational exam. In my opinion, the purpose of collecting mobile phone numbers by registered institutions is actually that some people want to sell private information to those training institutions for profit, and the rest are useless. Avoiding revealing your privacy is the best way to reduce this kind of harassment and trouble.
