What does it mean to send SF Express to sign for the property?

It is possible that SF Express delivered the package and the buyer just went out. With the consent of both the buyer and the property, the property will be accepted first.

The courier agent signs for it, that is, the nearby courier agent helps the buyer sign for the courier, and then informs the buyer to go to the agent to pick up the courier. If there is an agent of the courier company near the recipient's address, the courier will usually put the courier at the agency and then need the agent to help sign for it. After signing for the courier, the agent will inform the recipient to pick it up.
