80% of the ancestors of the people in Taiwan were originally from the
Main-Land of China, my father was from the Ha-Ga group (race/tribe)
of Canton, China.
All of the ancestors of my father's side of the family were married to
their own group of people, in one of the Ha-Ga Towns, they lived on a
small retail business that they owned.
My grand-father on my mom's side was from SzeChuen, China; migrated
to Taiwan during the time of war, married my grandmom from Taiwan.
He often mentioned how he join the military at the age of 16, and relocated
to Taiwan with military.
My grandpa did not speak any Taiwanese when he married my grandmom,
they communicated to each other with sign/body-language.
Altho it was the time of confliction of politics and differences, but my
family took and accepted it well.
