What is the original name of the movie? , which is the Yellow Sea, has nothing to do with translation. The Yellow Sea is located between China and South China, but it is not owned by either country alone, which is used as a metaphor for the Korean identity in South. In terms of blood, Koreans in China are the same nation as Koreans, and the life track of many Koreans is to go to Korea when they grow up (especially the older generation of Koreans), but so far it is difficult for Koreans to recognize and accept them. Because after the establishment of diplomatic relations between China and South Korea, Koreans began to work in South Korea, and engaged in 3D (difficult, dirty and dangerous) work in a large number. At the same time, some unruly Koreans committed some criminal cases, which led to the fact that most Korean people regarded Koreans as China people (Koreans did not have a high degree of affection for China people), which shook the Korean people's identity (being the same nation as Koreans). This film is mainly to show the confusion of Korean identity. I recommend you to watch it.
