Human memory practice cannot be separated from technology, the social platform is like digital archives, allows many memories to be stored and displayed in an open and online environment. Seemingly unrelated “strangers” have also become the focus of reminiscers’ memory practice under the interconnection of human and object, and have transformed into the “ memory of the multitude” in the public search of the subject. Behind the practice of “seeking memories of strangers”, old photos, algorithms, and other factors together form triggers for memory and relationship connections. In the interactive trajectory laid out on social platforms, the “past” and “present” are connected across time and space, shaping a dynamic “vertical synchronicity”. More importantly, the unfolding of memory practice is not the end point of the activity. The “connection” between the reminiscer and the “stranger” establishes a new communicative relationship, continues to write new memories, and the “past” “present” also approaches the “future” in this artistic conception. However, there is also a situation of "inability to connect" behind the connection and memory outreach, which not only reflects the exercise of temporal and spatial power by memory stakeholders, but also highlights the significance and value of connection, as well as the “instability” and “unknowns” of connection itself, and provides us with a new perspective to rethink and extend Connective Memory.
