That video is great to see. The acceptance of mixed race Korean's was a problem in the past and I am happy to see the warm reception that he is getting. Did you see the smile on his mothers face just a great video.
My kids are bi-racial Asian. I am happy to see that people are starting to put away those old beliefs. With each generation the world gets better.
I think Korea is still a homogenous country. It used to be that the mixed race children came from american soldiers and korean mothers. Now in Korea, there is a different situation developing. It seems that young people in the provinces no longer wish to farm, and as soon as they are of age, move to the big cities, mostly seoul. This is true of the women. The men who do stay and work the farms find that they do not have the opportunity to find wives. A lot tried to solve their problems by drinking. About 15-20 years ago, these farmers started getting picture brides or had arranged marriages with women from vietnam and the philippines. These women got married to these korean farmers, and they started having children. Some of the wives became homesick and left korea. Others may have suffered abuse from their alcoholic, frustrated husbands. I forget what the korean word for it is but now these children of mixed marriages are teenagers and older and are treated like outcasts.
Japan has the same sort of problem in that no one in the country areas want to farm anymore. But I do not know if the solution to that has been importing picture brides or having arranged marriages.
