签约 (qiān yuē): 契約や合意書に署名する

After repeated negotiations, the two sides finally reached an agreement on the price and delivery date, and officially signed the contract yesterday afternoon.

This singer signed with a very famous record company and will release his first album next month.

After graduating from university, he signed a contract with a tech company and became a software engineer there.

Before signing the contract, the lawyer reminded her to read every clause in the contract carefully to avoid future disputes.

Because the two sides could never agree on the profit-sharing ratio, the cooperation ultimately did not result in a signed contract.
