His mother, Bùi, worried about him constantly. She told us: “he had to walk by himself to school every day despite not being able to see bicycles coming his way, making his daily journeys quite dangerous.”
To keep him safe and out of harm's way, Bùi would often keep him inside the house, as when you can’t see clearly, even walking out the front door can be scary.
This also meant that he was unable to do a lot of the things that he loved – like playing outside, riding his bike and exploring the riverbanks near his home in Hau Giang Province, Vietnam.
