Nice post, but I'm not sure what your obsession with stop signs is.
This is an FYI post. The hakkas are Chinese, not the Taiwanese aboriginals. They are the smaller Chinese emigrant group that went to Taiwan from during the 18th and 19th centuries. In mandarin pinyin system it is kejia -- guest people. They are not aboriginal, like A-Mei for example.
People who've come from families where hakka is spoken are maybe a quarter to 30% of the population.
I do not seek your affirmation. Did your usual crack & cheap whisky medication wear off?
FYI...on the Island of Taiwan, formerly known as Formosa, the ethic group currently referred to as 'aboriginal' is popularly designated as Hakka or Hoklos. On this previous Saturday and Sunday the annial Hakka Memorial Ceremony was held in Taipei at the Taipei City Hall Square. Taipei Mayor Ma Ying-jeou spoke in Hakka asking the Yimin ancestors to guard over the country and its people. Hakka is a separate language. As is Taiwanese; as is Mandarin Chinese (the prevailing Chinese dialect on Taiwan). The Taiwanese Aboriginal affairs office, the Council for Hakka Affairs is headed by Lou Wen-jia, who is Hakka. This is a 'Cabinet' level office.
The word Hakka means "guests." It may have stemmed from the facts that the Hakka seemed to be guests to the locals when they migrated to their areas.
They appear to have their ethnological roots in the Central Plains region of mainland China; but there is record of 5 major migrations from this area.
Their recorded history strecthes 1,600 yrs, and their numbers have grown to over 65 million. There is currently an estimated 4 million Hakka living on Taiwan.
I do not presently have a date on their migration to Taiwan, but they appear to be the first group to have established permanent residence and culture on the Island. They currently are accorded "Aboriginal" stature under the laws of the Island.
Their language is unique to them. Their dress is unique as are their cultural and village legal system and local governmental affairs system. They also have their own Temple's devoted to the 'Yimins.' This is to honor those Hakkas who sacrificed in the fight against rebel oppositions movements against the Ching authorities in Taiwan.
As I made clear, I am not an expert on these matters. This is just a brief overview of the Aboriginal culture group known as the Hakkas on Taiwan.
