I really like Wulai (烏來) in Taipei county and try to get up there whenever I can. On one trip I snapped a picture of a very odd sign. It’s in Taiwanese and some form of pinyinized aboriginal language. I would guess it’s Atayalnese (The Atayal being the natives in Wulai), but can’t quite be certain. It certainly made me stop and look twice, though.
