Catalogue published on the occasion of the group exhibition 'Energy of Time' at CHANG ART, Beijing on view from 1 August to 1 September 2009. Includes artists' biographies.

'The exhibition features the works of Wang Guangle, Liu Wentao, Liang Shuo, Wang Yifan, Yan Bing, Yang Xinguang, Kang Haitao, Wu Di and Wang Sishun, all of whom have adopted "time" as a key conceptual element in their works. Two approaches of the mutual transfer of "time" and "energy" can be observed throughout their works: First, the creation of energy, as in the works of Wang Guangle, Liu Wentao, Wang Sishun, Yang Xinguang and Yan Bing, was completed in the form of artists' time accumulation. Second, time was leveraged as a conceptual element in the creation of the works of Liang Shuo, Wang Yifan, Wu Di and Kang Haitao. And of course some works, such as works of Wang Sishun and Yang Xinguang, adopted both approaches.' - excerpt from foreword by Xia Yanguo
