Series such as Window, Wall, City, and New York Streetscape reflect Wang Wulong’s sustained observation of architecture and physical space. In these works, doors, windows, walls, and architectural structures are no longer merely functional elements, but become important mediators that define space and connect the inner and outer worlds. Through the continuous reduction of visual elements, the artist seeks to reveal the order, boundaries, and poetic qualities of space itself, reexamining the relationship between people and their environment through a minimalist visual language.
