From the southern literature during the Japanese colonial period, the Post-war memory writing of the PacificWar, to the southern Sinophone literature written by writers from the Southeast Asian countries, the southern imagination emerged repeatedly is undoubtedly an important issue. In recent years, Taiwanese millennial writers have consciously written about the South, showing a new stage of the southern imagination. This paper intends to discuss the Southern vision in Mingwei Lien's "The Confession of Blueberry Nights" with the hope of outlining the new vision of the South in the early 21st century. This short stories collection uses a Taiwanese working holiday maker who worked in a five-star hotel in Canada to describe the life traces of the subaltern southern immigrants from Africa, Asia, and South America. On the other hand, it brings out the issues of "working holiday" and "Taiwanese migrant workers" and other important debates in contemporary Taiwanese society.
