How to sign someone else's works?

When copying other people's works, in order to respect the original author and avoid misunderstanding, you can make appropriate comments at the signature. The following is the specific way of expression:

1. Add your signature, including your own signature, pen name or abbreviation, to the appropriate position of the work (such as the bottom or corner).

2. If some elements of the original author are changed or deleted during the copying process, you can indicate "Copy from XX works and modify" or "Copy from XX works" in the signature.

3. Ensure that the information of the original work is accurately retained when signing, including the name of the original author, the name of the work and the year of creation (if known).
