The annual production of blood waste from slaughterhouses worldwide is approximately 45 million tons. These blood waste, if left untreated, can cause serious pollution to the environment. So I tried to use blood to create a material that could replace leather, as a critical reflection on the social issue of resource waste. From a professional perspective, this is closer to research in the fields of science and biology, but in the era of interdisciplinary integration, the relationship between humans and nature, as a complex and long-term proposition, is no longer limited to a certain identity of oneself, but should be broad and universal. In terms of design, I chose Mary Jane's shoes and pointed boots, which have strong cultural symbols and high historical recognition, as the design carriers. By combining blood as a new material, I aim to break traditional fashion boundaries, blend ancient and modern, nature and industry, fantasy and reality, and showcase a new visual impact and artistic beauty. This design concept is also used as a fable to discuss the contradiction between the right to life and industrial civilization, calling on humanity to cherish natural resources and pay attention to environmental protection.
