On what can honey fly back

Hello! Bees rely on their sense of smell to return home, bees have a very sensitive sense of smell, they can smell the smell in a very distant place, and can use the smell to identify the location, just like we locate, as long as they do not suffer accidents on the way, they will not be located wrong. Bees fly out will leave the smell along the way, so that after the honey, it can return along the way.
