Well, being Hapa in Brazil is the most common thing you can imagine, since the country inhabits the most amount of mixed races in the whole world.
I think that to be Hapa is a genetic gift, because you can take the best of various cultures and ethinics assemblances, and by mixing all together you got a very good masterpiece :D
I’m overwhelmed by my chinese part, and I really like it, I simply love the Asian culture and beliefs. I feel complete being Hapa.

I like your comment about hapa being a genetic gift. It something to be to cherished. You get the best of big worlds, and because of this you can find it easier to relate to others. Being hapa is a blessing is disguise :)
