I'm from Luoyang, and I'd like to ask how much the school newsletter charges. I remember saying it was three yuan a month. But now it's five dollars a month. What happened? ...

There are two kinds of school newsletter: one is to charge 5 yuan every month, and the other is to charge 9 yuan every month (no school newsletter fee is charged in winter and summer vacations). Monthly subscription in 6 yuan is the fee for teachers to send text messages to parents, and monthly subscription in September is the fee for sending text messages and 1 hour communication. Children can call their parents, and the phone numbers are four phone numbers or mobile phone numbers designated by their parents.
