In order to capture the data, we went to the library again, checked the relevant archives, borrowed and read 「The Housing of the Working Classes Act, 1890 & Quarry Hill Unhealthy Area, 1900 reference 1」. These first-hand materials not only provided us with the details for constructing the narrative, but also enabled us to understand the relationship between the project and the class. These primary sources not only provided us with details for constructing the narrative, but also enabled us to have a more systematic understanding of the social context and policy evolution behind the project. At the same time, we also conducted some filming about the video content inside and outside the library to record this process of dialoguing with the past through images.
