In 2022，marine folk customs have demonstrated their unique charm and cultural connotations in the process of closely integrating with tourism. They have also received key attention from communities，administrative departments，scholars，tourists，etc. The characteristics of interdisciplinary and multimedia development are particularly prominent. In addition，the development of large data and digital media technology has further expanded the space and possibilities for the development of marine folk customs，and of course，it has also brought about issues such as intellectual property protection. In addition，it should be noted that the primary attribute of folk customs is cultural attributes，followed by commodity attributes. Therefore，strengthening the basic theoretical research of marine folk customs and exploring its connotation and extension is fundamental. On this basis，through legislation，cross regional and cross-border cooperation and development，we will develop high-quality marine folk customs in a hierarchical and focused manner，optimize resource allocation，attach importance to the combination of “material” marine folk customs and “human” marine folk customs，create a good cultural ecological environment from the perspective of cultural ecology，and stimulate people to consciously and actively inherit and develop marine folk customs，taking into account the current social background of a large number of migrant populations，It is an important way for the sustainable development of marine folk culture in the new era of social change.
