It is difficult for people to construct a collective memory. Perhaps the common single history is an illusion and was deliberately created. Its indestructibility is consolidated by screening, erasing, and silence. Therefore, when every individual try to reconstruct history, he will find that there are many contradictory vacancies that cannot even be added to emerge or diverge from such a great history. In this process, it is precisely because there is no way to find a collective conclusion to rationalize the piecing together or constructing objects that are not related to each other into an exhibition, making the "vacancy" a perceptual experience that can be clearly realized in the present. This vacancy Therefore, it will continue to make people want to find the language of statements and become a driving force that makes people continue to speak.
