To break the stalemate of today's cross-Strait relations, China has formulated a series of policies recently to promote cross-Strait exchanges and in the end to create pro-unification interests in Taiwan society. One of the key elements of these policies is hosting student teams from Taiwan for a short visit to China. Since the year 2004, these student teams have attracted thousands of Taiwan college students each year and through these teams, the students had first-hand contacts with the Mainland Chinese society. But to what extent might these contacts change the students' perception of China and modify their identity over nationality issue? According to our interviews and questionnaires, we find that through these contacts, the images of Mainland China and CCP have been significantly improved while little changes have been made regarding these students' political identity.
