HK Community in Taiwan?

I’m working with a few clients on an intercultural program. They are from HK and wondered if there were any groups or associations that are made up of people from HK living in Taiwan? A Google search and a Forumosa search both proved fruitless. Does anyone have any knowledge on this subject?

Thanks!

My Dad and his colleagues are come from HK. They are working an regional hospital in Taoyuan.
