A pair of twin sisters who used to play different disciplines of volleyball have reunited on the sand, hoping their unique connection will take them far at this year's National Games when competitions kick off this Friday at Victoria Park.

As with many other identical twins, To Wing-tung and To Wing-man have their fair share of similarities and differences.

Both grew up playing volleyball, with Wing-tung honing her skills on the beach, while her younger sister took a more "conventional" approach to the game by sticking to the hard court.

The pair rarely crossed paths, and represented Hong Kong in their respective disciplines as recently as the 19th Asian Games in Hangzhou two years ago.

But that all changed when Wing-tung asked her sibling to join her on the sand.

She admitted their initial partnership wasn't always smooth, as they had clashed over different opinions and needed time to understand each other's perspectives.

"At the beginning, I felt confident that I could do it all, and that I could condense everything I had learned over the past 10 years and pass it to her in a short period," Wing-tung said.

"I wanted her to avoid all the unnecessary detours and achieve results in the shortest time possible. However, in that moment, condensing everything made it hard for her to understand or accept or she may struggle to execute it."

Wing-man expressed deep gratitude for her older sister's patience as she adapted to a new environment and rules.

She was grateful to be able to spend much more time together.

"When I played indoor volleyball, I rarely saw my sister because she practised in the mornings and I practised in the evenings. We only saw each other occasionally while eating dinner together at home," she said.

"After we started playing beach volleyball, we've actually been spending a lot of time together, eating and practising.

"We like to buy things in sets when we walk by and see something beautiful. We already wear the same swim trunks and tops for competitions... it was actually quite sweet for our relationship."

Of all matching items, Wing-man said the snowflake necklaces they both wear were extra special.

"It's meant to convey a message that (our) careers aren't long. We don't have much youth or time to waste. Like snowflakes, they will eventually vanish. So, we must cherish the present moment. Cherish practice time, cherish every competition, and enjoy this period of our athletic career."

Looking ahead to the National Games, Wing-tung hoped their connection will spur them on.

"I really hope we can aim for the top eight, and if possible, try for a medal... After analysing each match, we've identified some opponents we can compete closely with and possibly win against.

"The most important thing for us is to perform consistently. If we can secure the top spot in our group, our chances of making it to the quarter-finals will increase significantly and become relatively easier."
