Signing means "signing" in English, which usually refers to the act of signing at the end of a formal document, letter or contract. Signature records the name, position, date and other information of the signer and has legal effect. In business communication and cooperation, signature plays an important role, which reflects the signer's integrity and sense of responsibility.

In addition to appearing in official documents, signatures can also appear in some informal occasions. For example, personal writing, painting or photographic works often need to be signed after the completion of a masterpiece to indicate the author and creation time. This can bring more attention and recognition to the author, and also facilitate readers or viewers to find other related works of the author.

In short, a signature is not only a simple signature, but also reflects the identity and credibility of the signer. In modern society, it has strong cultural and legal significance and is an indispensable element in business cooperation, artistic creation and legal documents.
