documents: #Person1#: Hi, Natasha, how's life?
  #Person2#: Great. My family came to visit me.
  #Person1#: Oh, you must be very happy. How many people are there in your family?
  #Person2#: My immediate family is very large. It's my mother, my father, my two older brothers, my younger sister and me.
  #Person1#: I have a small family. They are my parents, my younger brother and me.
  #Person2#: I thought you were the only child in the family. Didn't China practice the only-child policy in the early 1980s?
  #Person1#: Yes, it did. But my parents are ethnic minority people. It's a preferential policy for an ethnic minority family to have two children.
  #Person2#: Interesting. What do you think about families with only one child?
  #Person1#: The child must feel very longly. My younger brother is 10 years younger than me. Before he was born, I used to be the only child and always dreamed that I would have a younger sister or brother one day.
  #Person2#: Do you get along well with each other?
  #Person1#: Yes, we are very close. He is 12 years old now and very smart. He always makes us laugh a lot.
  #Person2#: You are very lucky to have such a nice family.
  #Person1#: Thank you.
