North Korean Manpower Daoshan (Seol Gyeong-gu Xue Jingqiu), formerly known as Kim Shin Luo, was so powerful that he was recommended by talent scouts to travel across the ocean to Japan to learn sumo. After some hard work, his strength finally ranked third in Japan, but because of his Korean identity, his strength could not be further recognized. Disappointed, Li Daoshan drank and fought all day and got to know a wrestler from the United States in a fight. So Lidaoshan decided to turn from sumo to wrestler and rushed to the United States to study. A year later, Li Daoyama returned from school and brought this still fresh sport back to Japan. He defeated the American wrestlers in the ring, made the dejected Japanese people excited after the war, and became a national hero overnight. But his legend came to an end as quickly as he had previously expected.
