Xinyi Cheng's 2018 work *Iwa-Enogu on paper* employs the traditional Japanese mineral pigment known as iwa-enogu, celebrated for its rich, matte texture and luminous depth of color. The piece reflects Cheng's ongoing exploration of intimacy and the human figure, rendered with a quiet sensitivity that balances delicacy with presence. The material itself becomes central to the work's meaning, its ancient origins lending a contemplative weight to Cheng's contemporary figurative practice.
