If you're interested in Chinese archery then ATARN (
http://www.atarn.org/frameindex.htm) is a good place to begin to search, it was run by Stephen Selby who wrote a great book on Chinese archery (
http://www.amazon.co.uk/Chinese-Archery ... 9622095011) and is now run by Peter Dekker of the Netherlands. I've met Peter and bought an antique Chinese spearhead from him, very nice guy, he has travelled to China, Korea and elsewhere to research Chinese archery and often takes part in events around the world.
I think Peter wrote at least on of those articles in Journal of Chinese MArtial Studies, I think Steven Selby wrote one on Chinese bows.
The other person I know who is very interested and practices Chinese (manchu style) archery is Scott Rodell in the USA. His website (sevenstarstrading.com) sells chinese archery equipment from China.
Both Scott and Peter are active on facebook groups related to Chinese weapons and Asian archery.
I'm sure if you search around you'll find more people and resources too.
