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 . 

Yes
