Zhang Huan's *Moving Stone Memory Door* transforms a reclaimed door into a powerful woodcut surface, merging the weight of personal and collective memory with the physicality of salvaged material. The work reflects Huan's ongoing investigation into impermanence, cultural identity, and the traces left by human existence, using the door as both a literal and symbolic threshold between past and present. The interplay between the carved wooden surface and paper underscores the tension between endurance and fragility that defines much of his practice.
