According to the artist, immigrant workers who have traveled from the rural areas all over China to earn a living in construction sites in Chinese cities, are the most important members of the Chinese race, who are shaping our physical reality. Yet, they are the faceless crowd who live at the bottom of our society. To cast them in resin is a way to recognize their existence and contribution as well as to capture a fast-changing point of time in the Chinese society. From 2003 to 2005, Zhang has portrayed 100 immigrant workers in life-size resin sculptures of various postures, with a designated number, the artist’s signature and the work’s title “Chinese Offspring” tattooed onto each of their bodies. They are often hung upside down, indicating the uncertainty of their life and their powerlessness in changing their own fates.
