We still have one more day to go before we return home . What will we see tomorrow ?   no idea . We've enjoyed both the natural scenery and the city sights . What else is there to see ?   what about a factory tour ?   you mean visit a factory ?   yes . I heard there's a lager motor company nearby which open to the public every weekend . We can go to see how a car is manufactured and learn more about the automobile industry .   good idea ! I've always been interested in that . How much is the entrance fee ?   I'm not sure , but as far as I know , most factory tours are free . They are sponsored by the company providing the tour .   really ? What do the companies do that for ?   I believe most of them think of it as good public relations . They can promote their product and make their company better-known .   oh , i see . So factory tours are good for companies as well as visitors .
