How can parents send messages when they are cheated by teachers?

Immediately remind parents who have not paid in the group not to be fooled, and call 1 10 to call the police.

In the future, if the class teacher publishes the charging information in the group, the parents of the students can directly call or send text messages to the class teacher to communicate and verify, or confirm the payment after the children come back from school. Don't scan the QR code payment from unknown sources among parents to avoid being cheated.
