Notification format:

1, title.

There are three ways to write the title: one is "Lost and Found", and the other is "Lost and Found Notice".

2. Text:

The content of the text should be very simple. Only the name of the thing found, where the owner went and who to claim it from should be written on the claim notice. If there are many items, such as a wallet, which contains various items, you can simply list the names of the items inside, such as "a certificate, a meal card, and several RMB", so that the owner can check whether it is lost. The number of the certificate and meal card and the number of RMB should not be written in too much detail to prevent fraudulent use.

3, claim address or contact information, indicate the claim address or contact number, etc. Finally, indicate the posting date.
