"Sub-Human" is a conceptual performance system and visual symbol that has been constructed by artist TAO Xinqi since 2019, which is essentially a projection and mimicry of the current society we live in. The Sub-Human can simulate anything in the world or become the mental projection of anyone. As figurative characters constructed by the artist, the Sub-Human's spirituality, body movement style, and performance format lie between the everyday and the non-everyday, the human and the non-human, the conscious and the unconscious. This concept questions the universal notion of the world's "real existence" and is destined for extension and the possibility of collaboration with other artists and multiple media. In this project, "The Butterfly Dream of Sub-Human: Persona Tales Collection," the "Sub-Humans" are "monitors of the society" and "collaborative devices" with a character perspective. During the three-month season, the artist explores two "ephemeral tales" of contemporary society and explores various possibilities of performance art with different artists, starting from the core of contemporary art performance and performance mediums.
