Hong Hyo-min devoted special attention to the youth. The background can be found in the connection with activists of juvenile movement after his studying abroad, along with a manifestation of affection for the youth. His interest in the youth showed a tendency to be extended to juvenile movement, juvenile literary movement, juvenile magazine and juvenile literature in the 1920s. He urged various organizations to be incorporated into the Joseon Juvenile Federation to maximize the capacity of the juvenile movement. His insistence is summed up as switching the direction of the juvenile movement, which is supported by the logic of a high-ranking movement. His juvenile literary theory was developed in a way that emphasizes interrelationship between juvenile movement and juvenile literary movement and suggests methods to improve the level of juvenile literature. Hong Hyo-min paid attention to the reality of the youth in the colonial era and emphasized the responsibility of writers for the youth. However, his opinions were shunned by the dominant juvenile literary forces under the authority of Bang Jeong-whan, and they disappeared behind history`s stage by factional activities from leaders of the juvenile literary movement. In addition, he continued to raise issues to clear up the tendency to be in sympathy with Japan which was prevalent in the juvenile literary works and urged writers to make efforts to publish literary creations. In this process, he showed subtle signs of a rupture that do not conform to the struggle guidelines of the organization despite the fact that he was an enthusiastic member of KAPF. If that point is a standpoint of Hong Hyo-min`s critical convictions, an implication involved in the juvenile literary theory has its significance.
