LI Pinghu presented his performing artwork About Light in Delighting Therapy during Thirty-Eight Solo Exhibitions in May 2006. The artist was laying in the ceiling of the showing room, an arm holding a chandelier through a hole until he became too exhausted to keep and finally left it to fall down. The entire process lasted for approximately six minutes which was recorded in this very video. A certain sense of "waiting" permeated into every single second of the performance as well as viewing experience. Artist waited for his physical energy running out whereas viewers waited for the occurrence of the accident. Finally, the chandelier fell down on the ground and the image was plunged into darkness after sparks of light and electricity.
