Dragonboat teams throughout Hong Kong had spent months preparing for Monday's Tuen Ng Festival races. One of those teams was Hong Kong's only dragonboat crew made up primarily of the visually impaired – the Darkness Fighters.

Their mantra is to "challenge the impossible", and their goal: to create a blind-friendly sports environment.

Our reporter Anne Chan attended the Fighters' training sessions to see how members of the team were able to conquer their limitations by rowing together.
