I have to say, I'm not finding much in English. I found out that the village of Tai O is located on Lantau Island. There is much news coverage of that locale in regard to a new International airport being built there, and I think an Asian Disneyland, as well. What helps is if you expand your search to Lantau Island. I found only a few things that may or may not be helpful to your query. I listed a couple of journals and newspapers that specialize in covering this region. I listed some articles I found. First off the bat, some contact information for librarians local to you.
