签名 (qiān míng): to sign one’s name; signature

The doctor handed me the surgical consent form and asked me to sign it after reading it carefully, indicating my agreement to the surgery.

After the reader meet-and-greet ended, many fans lined up with books to ask the author for an autograph.

The rental contract requires both parties' signatures to take effect, so the landlord and I agreed to sign together tomorrow afternoon.

This document is very important; you must sign it yourself and cannot have someone else sign on your behalf.
