This article studies the Development Process and Characteristics of Macau's modern chinese poetry, mainly exploring the locality, diaspora, and globality of Macau's modern chinese poetry. Macau is a Portuguese colony that has long been colonized and has a special history and culture adjacent to Hong Kong. Following the development of Macau's modern poetry, he analyzed the works of Chinese poets representing Macau from the 1920s until recently. This study shows the characteristics of diaspora and global characteristics as well as the mainland and regional characteristics in Macau's modern new poetry. Macau's poetry world, like Taiwan and Hong Kong, has also shown a tendency to create both modern and postmodern quotations, reflecting unique historical, social, and realistic characteristics of China's May Four New modern poetry tradition. Looking at these poets' works, we could see that Macau poets tended to interact with poets from Taiwan, Hong Kong, and Singapore more than with contemporary China. Furthermore, the poet Han-Mu and Tao-Li of Macao later moved to Canada, Singapore, and Hong Kong to create many works to express their homesick nostalgia and longing for Macau. From this point of view, Macau's poetry world should be considered further in its integration with the world literature, beyond its regional and mainland literary tendencies. Further discovering the unique characteristics inherent in their literature, it is necessary to revisit the characteristics of diaspora that expand into the Overseas Chinese literature of the world.
