Due to urban planning, the natural riverbank shoal along the Qingshan section has gradually diminished. Beyond the surveyed and regulated routes, only a narrow path remains, allowing passage for one or two people. The artist walks along this residual strip of land, collecting sediments carried there by the movement of water. Originating from different times and locations, these materials have been continuously eroded into rounded or oval forms. Bearing traces of upstream flows, they point to a former topography and pathways that have gradually disappeared.

In the video, the artist assembles the collected pebbles to reconstruct the interior layout of a former house from memory. The movement of the hands corresponds to a voice-over derived from the artist’s grandfather, whose oral descriptions form a spatial map of the dwelling. Through the gathering and reconfiguration of natural materials, individual memory and geological time are placed within the same structure. Between the motion of the hands and pauses in speech, a process of retrieving and rebuilding memory emerges, it serves as a sharp visual metaphor for how urban renewal severs intergenerational emotional bonds, seeking to preserve the traces of a home fractured by the relentless tides of modernization.
