People moving to cities in China

The Japan?Korea Treaty of 1905, also known as the Eulsa Treaty, deprived the Korean Empire of its diplomatic sovereignty.
Japan then signed the Jiandao Agreement with Qing Dynasty (China).
The Koreans in Jiandao who lost their country went up the Biyan Mountain to the pine tree pavilion (Ilsongjeong) to soothe their grief.
To regain their country, Korean independence activists went through all those harsh and dark times, wandering the plains of Manchuria. Their descendants in Yanbian have gone through the happiness of Korea’s liberation as well as the tragic division of the country.
A century has passed now. How are the descendants, the so-called joseonjok, living in Yanbian? What kind of changes are they going through?
We take a look at the lives and stories of Koreans living in Yanbian, China.
