Why are most of the supermarkets in North China goods, instant noodles of Master Kong, Wahaha mineral water, etc., which are sold to North Korea for several times and imported into China?
South Korea has a small area and a large population. Unlike China, China people are mainly concentrated in North China and Central China, and coastal cities have a large population. However, the central part is vast and sparsely populated, and most of the land is available for planting. However, there are few Koreans and there is no spare land for planting, so most of the goods in South Korea are imported.
