The 37-year-old climber, whose car accident 10 years ago left him paralysed from waist down, could not make it to the top of the 300m-tall Nina Tower on the Kowloon peninsula.

“I was quite scared,” Lai said. “Climbing up a mountain, I can hold onto rocks or little holes, but with glass, all I can really rely on is the rope that I’m hanging off.”

The event raised HK$5.2 million (US$670,639) in donations.

Lai, prior to 2011, was crowned Asia champion four times for rock climbing and at one point ranked eighth globally.

After his accident, he resumed climbing by attaching his wheelchair to a pulley system. Five years ago, he ascended the 495m-high Lion Rock mountain, a local folk culture symbol of Hong Kong’s strength and grit.

“Apart from just living, I wondered what drives me? So I began to chase that, knowing that there was a possibility I could climb mountains, even in a wheelchair,” Lai said.

“In a way, I forgot that I was a disabled person, I could still dream and I could still do what I liked doing.”

Although he did not make it to the top of the skyscraper, due to safety concerns, Lai hoped to send a message.

“Some people don’t understand the difficulties of disabled people, some people think that we are always weak, we need help, we need assistance, we need people’s pity,” Lai said.

“But, I want to tell everyone, it doesn’t have to be like that. If a disabled person can shine, they can at the same time bring about opportunity, hope, bring about light, they don’t have to be viewed as weak.”
