“The Form of Perception of the Invisible object” originates from a private conversation between Zheng Wei and Liu Guannan.
After self-censorship and to transmit the invisible, the visible part of the conversation was erased and made invisible, while the invisible part of the conversation was processed with sound and made visible, even though the “visible” was incomprehensible.
This sound artwork was first exhibited in the elevator cabin of a 30-floor hotel building（CHAO Hotel，Sanlitun，Beijing）.
