The Teacherage is a trilogy made on the basis of the social relation between Taiwan and the United States from the cold war period to the post-cold war era. Showing the specificity of the tertiary education resources distribution and component of manpower in different college communities in Taiwan and the United States. I analyze how the transformation of the international relations between Taiwan and the United States in nearly half a century affects the migration and self-governance of common people through the method of auto-ethnography. The project will discuss the migration of specific population, the effect of overseas returnee, and how the withdrawal of American aid causes the internal power reshuffle in a private university; I also reflect on my personal struggle from my parents' culture from their local/provincial background, identity constructed by a prestigious university community, migration of Taiwan and the United States, observation and growing up with the (post)colonialist experience.
