The idea of writing a message:

The format of the message is divided into four parts: title, body, signature and date. Write the word "information" in the middle of the first line. The address should be written in capital letters and marked with the recipient. Write the text on the next line and write clearly what you want to say to the other party. Write clearly who left the note at the bottom of the text, and write clearly the year, month and day in the lower right corner.

pay attention to

In daily life, if you have something to inform the other party, or if you have something to entrust to the other party, the other party is not here, but there is no time to wait for the other party to come back. Write a note to each other. This style is the message board.
