Contrasting vestiges of Taiwan's Mainlanders' cultural activities are presented through the research into cultural locations and major incidents as described above. The archive sets to bring about political introspection for this "over-politicized" group. From the perspective of the common people, the records and memories which had been ostracized by the country's politics are now included, so that individual experiences and emotions can be narrated and discussed publicly, so that the emotions and identity of people, among other facets can be seen. Currently the collection holds over 6890 entries.
