The repetition of landscape painting theme has existed since ancient times, and the theme of "travelers" plays a vital role in the evolution history of landscape painting. The paper, with case analysis and image analysis as the main research methods, takes the theme of "travelers" as the starting point to study its repetition and the reasons why this phenomenon can't be cut off in painting history. The focus is on the analysis of the "antique" tradition which has existed since ancient times and the influence of emerging "marketization" in the middle and late Ming Dynasty on landscape painting repetition. In this way, the study explores the manifestation and artistic significance of landscape painting theme repetition under the innovation of landscape painters. Then, we can see that landscape painters never reject the repetition of theme, but are very keen to choose the "old theme"; the "old theme" is not actually "old", and it can glow with new vitality in the new years and with new painters.
