Emma: What are you doing, Li Lin?
Li Lin:     
Emma: I have read it before, What do you think of the story?
Li Lin:      Yu Gong found a good way to deal with his problem.
Emma: Really?    It seems impossible to move a mountain.
Li Lin: But the story is trying to show us that anything is possible if you work hard!  Yu Gong kept trying and didn’t give up.
Emma:    I think we should try to find other ways to deal with a problem.
Li Lin: But what could YU Gong do instead of moving the mountains.
Emma: He could build a road.   
Li Lin: We have different options about the story, There’s many sides to a story and many ways to understand it.
Emma: Yes, that’s fine.
