I've been looking at Hong Kong racing quite a bit over the summer. The Hong Kong Jockey Club has a terrific website and all the information is free at
http://www.hkjc.com.
The HKJC run a tight ship. The main thing I like about their racing is their strict drug use policy. The use of Lasix, for example, is never allowed to be used -- even in training.
Contrast HK's drug policies with Kentucky's policies -- some of the most liberal in the world.
When I was managing a racing stable and raced out of Mountaineer Park our trainer would not allow us to claim horses that shipped up from KY because too many of them were only able to race with the help of drugs. This was a widely held belief among MNR trainers and owners.
