签字

签字 refers to a person's name written by hand, typically used as a legal or official confirmation. It is commonly associated with signing documents, contracts, or forms.

The character 签 (qiān) originally meant 'to mark' or 'to stamp,' and later came to mean 'to sign.' 字 (zì) means 'character' or 'word.' Together, they form the term for a signature, which is a personal mark used to verify identity or agreement.

Signing is an important part of many formal processes in Chinese culture, such as job applications, contracts, and legal documents. The act of signing is often seen as a symbol of commitment or responsibility. In everyday life, you might see someone signing a receipt, a contract, or even a gift.
