A 22-year-old man in Henan Province has managed to survive solely by drinking 15 kilograms of water a day - without ever eating a bite of food.
The man, Ning Xuefa, maintains that he established this unusual habit as a child.
"As a student, I would always attend school with a huge bottle of water, but I wouldn't ever touch food," he said.
After he dropped out of school when he was 14, he moved to Shenzhen, Guangdong Province to work as a manual laborer, but his weak body and frail constitution failed him time and again.
His father backed up the story that his son only drinks water and never touches a single scrap of food, including rice or steamed bread.
