In traditional type design, characters are typically constructed through an "additive" approach, using the eight strokes of Yong as the basic unit. In this design, I adopt a "subtractive" mindset, redefining Chinese characters through spatial addition and subtraction. The typeface's system is based on the geometric shapes of circles and squares—fundamental forms that provide a clear, modular framework for exploration. Beyond their philosophical and cultural significance in Chinese history, these shapes offer a logical and repeatable system for constructing new character forms. The design process began with digitally generated forms using computational coding, which enabled a rigorous study of proportional spacing and grid systems as potential structural foundations for Chinese typography. By systematically combining circles and squares, I aim to break free from the constraints of traditional strokes while maintaining consistency and allowing for creative variation. The interplay between these shapes creates dynamic negative spaces, redefining how characters are recognized and perceived. The visual results of this experiment were refined and developed into a set of 36 characters.
