FOR Eric Jang, the East Asian Games in Shanghai are more than just a tenpin bowling tournament. The 52-year-old Hongkong coach, who has a 12-strong team with him for the four men's and four women's events, was born in Sydney and has lived in Australia all his life. But his parents were from Canton in southern China and this is his first visit to the mainland. Jang, who was appointed full-time national coach by the Hongkong Tenpin Bowling Congress only six weeks ago, said: ''My parents emigrated in 1938 because they heard Australia was the land of opportunity. They decided to take the chance and, after a tough start, like all Chinese they survived and progressed. ''So for me it's a great experience to be here - to see the situation and to meet the people. I had visited Hongkong as a tourist and for my interview before taking up my post on March 26 but this is another world altogether.'' Jang's appointment is funded by the Hongkong Sports Development Board and he has a two-and-a-half-year contract, up to the World Championships in Reno, Nevada, in 1995. A former Australian champion and national team player, Jang left the sport for a few years to concentrate on business but had great success when he returned as a coach. And he believes Hongkong have a good chance of collecting a few medals against opposition from China, Japan, South Korea, Taiwan and Guam in the four disciplines - singles, doubles, triples and teams of five. ''We are very confident of doing well but from what I have seen of the opposition they look to be on an equal scale. ''We have two very experienced lady bowlers in Cat Che and M. C. Choi and they should acquit themselves very well. ''In the men we have two outstanding bowlers in Franco Lau and Frankie Cheung in the men's doubles.'' Competition begins this afternoon with the singles events, after which the coach will name the combinations for the next three days. Three more Hongkong teams will be in action on the first day of competition - badminton, gymnastics and swimming.
