PROBLEM: We can't go that way , the road is blocked for the next few days . Oh , that's right . They're filming a movie up there , aren't they ? Some high speed chase scene , I think .

I don't know about all of that , but think about it , their business gets free publicity ! Oh , yeah , they get to be in a movie for the whole world to see !

SOLUTION: Yes

PROBLEM: Can I help you ? I'd like to buy some Chinese-style cakes . Could you recommend me some ? Certainly . What about moon cake ? It's typical Chinese food . Moon cakes ? What is that ? The moon cake is round and looks like the full moon . That's why it's called the moon cake and the moon cake symbolizes family reunion and harmony . Sounds very interesting . I'll buy some to family people . All the moon cakes are generally classified into two styles , Cantonese style and Suzhou style . What's the difference between these two styles ? The skin of Cantonese style cakes is soft and puffy with heavy stuffing while the skin of Suzhou style cakes is puffy filled with fragrant nuts . Get me some of each . OK , here you are .

SOLUTION: Yes
