I want to make up lessons for someone, but I don't know how to write a notice.

If you want to make up lessons for students, the notice of the cram school should be written like this and sent to parents' mobile phones:

Count your parents' cell phone numbers. The method is up to you. Ask the school teacher or the nearby property, and try not to miss any one. There is no problem with grandparents' figures. Anyway, just send it in batches. The exported numbers are in excel format.

2. After finding the number, import it, and then write down the content of the tutorial to be sent. It's very simple, including address+phone number+Chinese and math subjects. It will take 8 seconds to send it, and my parents will come when I receive your text message.
