Many of us have never heard of tchoukball - and a group of Hong Kong fans of this team ball game are set on addressing this.
Tchoukball is similar to handball. It was invented by a Swiss sports physician named Hermann Brandt 34 years ago.
He declared that the objective of physical activity was 'not to create champions, but rather to help and construct a harmonious society.'
A tchoukball match opposes two nine-player teams on a rectangular field, with a rebound frame (a small trampoline), placed at either end, and a forbidden zone around it.
To score a point, a player must bounce the ball off the frame in a way that no defending player can catch it.
'The attraction of this game is that there is no body contact allowed and it challenges players to think on their feet,' said Alex Pong Yiu-wing, a member of the Tchoukball Association of Hong Kong, China.
'Playing involves asserting oneself without dominating someone else. It is an easy game to learn and has strong educational power,' said Pong, who will help organise Hong Kong's first ever tchoukball competition at Ying Wa College on August 20.
