Where I live que have two different situations: the center where the people are more rich and the surrounding neighborhoods where poorest people live. The living conditions are very different for people who live just a few minutes from each other. I can cite for example the situations that my friends and I spend when we want hang out together: in the surrounding neighborhoods we have cheaper places to go, but these places are surrounded by violence. In the center violence is not much better, but several places offer a greater sense of security. Because of this and its location, as well as being frequented by richer people, they are more expensive places.
But these are small problems compared to education, healthcare system, public transportation among several other things that are quite different.

Thu Thảo,
Do you mean " The feed is still not full " - Không đủ ăn ?
I would write " They work in fields from early morning till late night. But they still can not be able to feed their families " .
Just my 2 cents.
