Ok. Are those koreans in that part of china are they former north koreans? Do any of them dream of going to south korea to somehow get a better standard of living?
The Koreans are recognized as one of the official 55 minority tribes in China. 3 million of them, called 朝鲜族, mainly in Jilin, Heilongjiang and Liaoning. They migrated from the Korean peninsula mainly during the 17th century, and later during the Japanese occupation and then the Korean war. Most of them are doing well, and would rather remain as Chinese citizens than suffer poverty in North Korea.
The Chinese have affirmative action for minorities like Koreans and Manchus for university entrance and certain subsidies. So the Koreans are happy there, and they are all bilingual in Mandarin and Korean. Some have assimilated into the Han majority through marriage. Not many dream of going to S. Korea.
A small percentage are present-day N. Korean refugees who risk life and limb to cross the border into China. If caught, they're deported back by the Chinese authorities. Those who escape successfully stay on illegally in China. Some go to the South Korean embassy to seek entry into S. Korea. Many who went to S. Korea ended up being discriminated against and bullied in school and the workplace by their Southern compatriots who see them as uncouth country bumpkins, and some have actually gone back to China again where they are happier and don't face discrimination.
There are also some S. Korean Christian missionaries who have stayed for many years in N.E. China, converting the local Koreans to Christianity.
Actually honestly to tell you the truth koreans are the closest to the stereotypical mongoloid features of flat nose, wide face, slanted eyes. They are the closest.
Agree. The Korean language belongs to the Ural-Altaic linguistic group which also includes Japanese, Mongolian and the extinct Manchurian languages. Flat, broad face, slit eyes, prominent cheek bones.
