Mr. Trần Văn Cường, 30 years old, and his wife, Mrs. Lê Thị Lan Anh, 29 years old, have three children: Trần Văn Quốc Hào, 9 years old and currently in the third grade, Trần Quốc Kiệt, 3 years old, and Trần Ngọc Khánh Đan, 2 years old. The family lives at 596, Thạnh Quí A Hamlet, Thạnh Phú Commune, Vĩnh Long Province. Mr. Cường works as a construction laborer, but his income is only sufficient to cover the family's basic living expenses. As a result, the family cannot afford to build a water well and must rely on water from neighboring households.
