16、I was shocked by the picture at first sight. In the picture, by a small river, a little boy had tears on his lovely face and an old man, maybe his grandfather, was wiping his tears. From the clothes they are wearing we can see that they are poor. The boy was sad. Is it because his parents are working in a place far away from home and the boy is missing them day and night?

I think so. At present, many parents leave their children at home in order to support their family. These parents have no choice. I hope something can be done to help these parents get back home as soon as possible.
