The idea of this project came from the many "second hand" platforms I use. The time spent abroad as an international student may be as short as one year and as long as four or five years. Therefore, the place we live when we are studying seems to be a temporary place and a temporary home in our life, and the intimate relationship we have with the items here is mostly temporary. The personal items on the second-hand trading platform are in this kind of "In the hollow" realm of affiliation. The large quantity of trades on second-hand platforms each day has made me think about the relationship between "people" and "objects".
