A few years later, Lu Isshin was sent further into the countryside to work as a shepherd in the Inner Mongolia Autonomous Region. On the grassland, he met Huang Shouhai, an overseas Chinese returnee from Japan, and learned Japanese. He also met Jiang Yue Mei, a nurse in the traveling medical corps who nursed Isshin through the night after he contracted tetanus. Hearing Isshin's wish to tell his adoptive parents about his situation, Jiangwolmei wrote a letter to Lu Dezhi. Upon learning of his son's false accusation, his adoptive father went to Beijing to help his son.
