Any Mountain or cross country biking clubs in or near kaohsiung? If not, anything similar? (ie, mountain climbing, hiking, camping, kungfoo 
)
Head over to forums.formosanfattire.com - and ask - there are a few GaoXiong riders on the boards, I am sure they can help you out.
Also contact Mark Rochel at Blue Skies Adventures (rochem@ksts.seed.net.tw). This is a non-profit local
nonprofit hiking club.
