A 20-years-old video

This is a video taken in Hong Kong on 1-1-1988, while I was still a baby.
It was the Hong Kong National Orienteering Championship 87/88 cum Hong Kong Orienteering Club Championship '87. The camera man just walked around the event center and shooting at the competitors preparing for the race. I could only recognize Yeung Kwok Keung, not his face but his voice. Since Hong Kong was a colony of the Great Britain at that time, we can see quite a lot of western orienteers in the 4-minutes-long video. I think the number dropped sharply because of the coming of 1997. I hope they are still enjoying orienteering in their home countries.
I started orienteering in 2002. Until now, I can see no more than 10 western orienteers who are living here. As I know, most of them came from an orienteering club called Demon Orienteers. They bring their young children out for orienteering, just like most of the orienteering families in Europe. But vary few local parents do the same thing. I asked them why, most answered me that their children prefer playing NDS/PSP to running around the hills. Some may have interests on orienteering, but not at the top priority. I don't know why... Maybe orienteering is not a famous sport in Hong Kong, some schools even do not treat it as a sport. My secondary school moved the orienteering club from the "Sports Union" to "Recreational Activities" two years ago. Another club in that group is Magic Club. Can you see the reason now?
