A touching story of a wife using a rope meant to tie hair as a way to lead her husband while running for over 30 years has been circulating online and garnered significant attention.

"She runs for me. My wife is really good," said Lou Dexin, a 72-year-old blind man from Jinhua, East China's Zhejiang province. His wife Lou Shunguang is 68 years old.

Lou Dexin was not born blind. In his childhood, he injured one eye in an accident and the other eye had only weak vision, but he has always maintained an optimistic and cheerful attitude towards life.

At the age of 43, he had retinal detachment due to the overuse of his eyes and needed surgery. Before the surgery, he had to rest in bed and avoid strenuous exercise because his eyes were filled with silicone oil.

Ten days before the surgery, two children in the village were drowning. When they cried for help, Lou Dexin, who was lying on the bed, swiftly got up to save them. After a while of artificial respiration, the two children were rescued. Because of the force on his face, his retinas became more fragile.

After that, the death of his father dealt a great blow to him. He was completely blinded.

Lou Dexin suffered from depression due to blindness. In order to cheer him up, Lou Shunguang would tie a rope around him and lead him on a run. Holding a rope, the two of them have been running like this for 30 years.

The rope hangs on their hands and keeps the two moving at the same pace as much as possible. Finally, after falling down and getting up countless times, the two gradually merged. A subtle movement change can be perceived, and the distance between them is getting farther and farther.

In the eyes of outsiders, the two cooperate well while running. However, nobody knows how much effort was spent to get to this point. Lou Dexin and Lou Shunguang cannot remember how many times they have fallen and how many pairs of shoes have been worn.

The rope, a symbol of their love, has brought Lou Dexin out of severe depression. After the story went viral online, many netizens were moved and called it "the most beautiful long-distance love run".

"Taking my husband to relax and feel the wind fills him with happiness. I'm happy too. As long as he can run, I will run with him", said Lou Shunguang.

Over the past 30 years, Lou Shunguang said the most to Lou Dexin: "It's okay; I'll be your eyes."
