 Because we don't want the garbage to have direct contact with us. So it's kind of scary that they have to live there. And the boy that we found fed bear and running around in the garbage mountain. I don't think they feel something different about that. It's their daily life and they make money all of it. And I talk about what the meaning of education is and it really let me think deep on this. Education is about hope and it can bring hope to the children, to a family. And actually I saw many children outside ECS. There are no education and I thought they really deserved this. I mean I punch in by the reaction of a soul when he first see our video. Because I never think that our video can really touch someone. And I can see that he really have a passion in ECS because he know about an individual student story. So I can see that he really care about his children. And he also really want to make the ECS to be a better environment and to provide a better education for his children. For me the most impressive moment is when Anna told us that my column student come to help me with the salon he open next year. During the filming process we talk ourselves a lot and we are so afraid that we will influence their business and we will be trouble to them. When we know that he recognize our job and we did well, it really catch me a lot.
