On March 27, at the Postal Direct Delivery Center in Lishui District, Nanjing, staff were seen loading goods into autonomous delivery vehicles for timely dispatch to various service points. It is reported that the center has currently deployed 10 unmanned postal delivery vehicles, which operate automatically and safely along preset routes and stops. These vehicles primarily handle round-trip express transport between certain rural and township service points and urban stations, forming a notable "smart highlight" in the modern logistics industry.
