answer: Aunt Shirley explains the naming of the Lantern Festival to #Person1# and recommends Yuanxiao, which is a must-try snack of the street fair, like Tangyuan but with both sweet and salty fillings.
documents: #Person1#: Aunt Shirley, I heard the Yuan Miao Festival is the name for the festival. Why did it get its name?
  #Person2#: Well, the first lunar month is called Yuan-month, and in ancient times people called night Miao. And you know the festival is just in the middle of the month.
  #Person1#: Oh, I see. I also heard today is the last day for the street fair. Can't wait to sample all the snacks.
  #Person2#: Sure. It's indeed a culinary heaven which offers a wide range of delicious snacks to satisfy all tastes. Then, which one would you like?
  #Person1#: Can you recommend some must-try?
  #Person2#: OK. Let's go over there. For the Lantern Festival, you should never omit the Yuanxiao.
  #Person1#: What's that? It gets the name from the festival itself. That's really funny!
  #Person2#: Actually, they are small dumpling balls made of glutinous rice flour. They are like Tangun.
  #Person1#: Oh, I know Tangyuan. It's a sweet snack, good for dessert.
  #Person2#: Yes. And also, we can find Yuanxiao with both sweet and salty fillings.
  #Person1#: I'd like to try the salty ones. Where does that strange smell come from?
  #Person2#: Oh, the smelly bean curd. My favorite!
