The drone can carry individual packages up to four kilograms, while oversized or overweight mails are still handled by local postmen. /Xinhua Photo

Employment of drones helps shorten delivery time thus improves efficiency for local post service. It only takes a drone 10 minutes to cover a postman’s two-hour travel. /Xinhua Photo
