The City of Memory explores past memories and experiences. This work crosses the boundaries of time and space, delving into a city made of memories. Through this piece, the author questions how we remember the past and understand the present. Traces of the past never vanish completely, but they can fade over time. While we live reminiscing the past, those memories are not always accurate. Despite this, we can still feel the pulse of life reflected in different times. If we could travel back in time, we might imagine how the world could change.
