There is little to no personal space in a 1-room flat. Some families use curtains or pieces of furniture to create a sense of privacy.
With their parents working long hours, children in these families are forced to grow up more quickly than their peers. From a young age, their responsibilities include doing housework and taking care of themselves and their younger siblings. They may even take up part-time jobs as teenagers.
Every dollar counts. If someone falls sick, it can be too expensive to visit the doctor and get medicine. It is a luxury to buy new school supplies or clothes, let alone the latest electronic gadgets.
