Zhang Hua: A children's story book. What's your book about
Wang Hai: It's science fiction. It's about man's future life.
Zhang Hua: Which book is more interesting
Wang Hai: It's hard to say. Some people think science fiction is more interesting than children's stories, but others may prefer children's stories to science fiction.
Zhang Hua: Right. But I know many people like detective stories.
Wang Hai: I like detective stories, too. They are the most interesting stories of all. But we must read different kinds of books.
