Fit trip: Chief Executive Donald Tsang joins martial arts enthusiasts to practice tai chi.

More than 20,000 people practiced tai chi together for 20 minutes at the former Kai Tak airport today, setting a new record for Hong Kong and celebrating the special administrative region's 10th anniversary.

The Mega Tai Chi Show, jointly organised by the Leisure & Cultural Services Department, the Wushu Union, the Chinese Martial Arts Dragon & Lion Dance Association and the Tai Chi Association, offered martial arts enthusiasts an opportunity to exchange knowledge and skills with local and Mainland masters.

Chief Executive Donald Tsang opened the show today with six renowned Mainland masters and representatives of the three tai chi organisations giving demonstrations.

The department held a similar event in Happy Valley in December 2001 when more than 10,000 people took part, setting a record in Hong Kong for the number of people performing tai chi.
