To their neighbors in Ho Chi Minh City, the sight of Gia Hung carrying his twin sibling Gia Lam on his back to school has become familiar over the last several years.
Nguyen Gia Hung and Nguyen Gia Lam are twins and 8th-grade students in District 10.
While Hung was born normal and healthy, Lam suffered from Tetralogy of Fallot, which is a birth defect that affects normal blood flow through the heart.
