The 3,142-meter ascent will be a considerable physical challenge for Son, who is only 83 cm tall and weighs 23 kg.
Born to a Vietnamese veteran father who was exposed to Agent Orange during the war, Son suffers from porous bones and muscular atrophy, which has severely limited his movements since childhood.
Lam said he wants to change perceptions about people with disability and raise fund for “Son Lam and friends,” a charity he runs to help needy children.
He has been training for the trip for months, climbing stairs and practicing martial arts.
“I will wear a T-shirt with the Vietnamese flag and sing our national anthem when I reach the top,” Lam told Tien Phong newspaper.
The 28-year-old is famous for his academic achievements and actively working to raise awareness of people with disabilities and helping them despite his own condition.
He has two college degrees, speaks four languages, and is a sports editor at The Thao Van Hoa newspaper.
