Couple defy disability to become proud parents

As is customary in China, Zhang Yongfei and Tian Xiao held a family celebration this month to mark the 100th day since the birth of their son. Unlike most new parents, however, Zhang will never see his child, and Tian will never hold him.

"You are my eyes, and I am your hands and legs," Zhang, 32, who was born blind, told his wife at the party in Taiyuan, Shanxi province.

Tian, 27, has Lou Gehrig's disease - also known as amyotrophic lateral sclerosis, or ALS - which is a progressive condition that attacks the nerve cells that control muscles. Over time, it leaves patients struggling to walk, speak, swallow, and even breathe. So far, there is no cure.
