this text offers some informative insights for a greater understanding of formosa, taiwan r.o.c.. i recommend reading this book to become acquinted with urban and rural customs. read the book but don't pack it for the trip - if you follow this book (or any other) you'll miss the wonders of detail, suprise, and enlightment.
i suggest flying to the international airport in kaohsiung, spending a few days, take a slow train north along the eastern coast and visit taipei. taichung city (west coast, central) is much more comfortable, and less foreigners are found.
