The national image and sportsmanship in the international sports events frequently undertaken in the recent year are grasped as effective cultural value output. The research focuses on the significant communication characteristics of the sport's slogans in terms of motivation and mobilization, and uses cultural translation to leap across the initiative of different cultural subjects to compare and analyze the visual design of slogans of international sports events in recent years, and construct the method of cultural translation of national images in the three aspects: expression connotation, visual innovation, and media application, in terms of visual design of "meaning", "form", and "use" at the cultural level. The national image in the communication of international sports events is reconsidered through the practice of visual design, which once again defines the translation and communication of the visual design of the slogans of international sport events when different cultures gather, with the aim of providing reference for the communication methods of national image culture in China's international sports events.
