This group of people who have been deprived of their dignity are struggling to survive under the pressure of persecution, humiliation, disease and death. People can't drink tap water, they can only drink the bitter water in the well, and they have to run half a mile to go to the toilet. Whenever the rainy season comes, the water in the sewer rises and overflows and enters the poor people's homes, stinking and miserable.
