A Hong Kong dancer left paralysed after being struck by a giant screen at a concert by popular boy band Mirror has for the first time shown himself moving independently in a wheelchair in a social media video since the accident 3½ years ago.

Dancer Mo Li Kai-yin, 31, shared an Instagram video on Saturday of himself operating an electric wheelchair with the caption, “A 90 per cent introvert be like:” followed by a bashful emoticon.

In the clip, he appeared to be in good spirits as he steered the wheelchair using his right hand. Upon noticing someone filming him, he shyly reversed away.

He added the hashtag “please let me go” and joked in the caption: “Extra motivation to train for driving: To get away from the crowd.”

Li also playfully tagged three friends, including Canny Leung Hoi-ching, who was also a dancer for Mirror at the concert where the accident happened.

Saturday’s video marked the first time Li has shared a video that showed clearly his motion ability since his injury.

The footage reveals the stoma on his neck and shows him wearing a mask while performing movements such as lowering his head, shaking his head, and moving his right arm.
