The space has a high ceiling: 444.5 centimeters wide, 494 centimeters deep, and a height too tall to measure, probably more than 600 centimeters. No windows. The inclined skylight on the ceiling keeps the space brilliantly lit all day. And then, I use my own method to understand and confirm this space that I am about to spend four months in: measuring, measuring numbers with numbers. Because I cannot add lighting, my numbers first gained color in this white and pure space. Although I cannot create a space for shadows through lighting, natural lights and shadows appear naturally in the afternoon, by chance rather than desire, a kind of placid and faint surprise. With square pieces of paper with different sizes as units, I draw, cut, and completed the measurement of the studio twice. I ended up with two parallel lines, two different measurements. During open studio, I receive these questions in abundance: First place, most abundant, "How did you stick these numbers on there?" Second place: "Why numbers?" Third place: "Besides numbers, do you also use letters?" Fourth place: "Are these numbers in a certain sequence?" Despite so, there was still someone who asked me if this work has a relationship to the space, someone who saw the void in the squares on the ground and the fullness of the numbers on the wall, someone who noticed those upside-down shadows. I also made another work based on numbers measuring numbers; it's about my height.
