Zhang Huan est un artiste chinois né en 1965 à Anyang, dans la province du Henan. Il vit et travaille entre Shanghai et New York.
Family Tree est un projet réalisé en 2000, au sujet duquel Huan dit : "I invited 3 calligraphers to write texts on my face from early morning until night. I told them what they should write and to always keep a serious attitude when writing the texts even when my face turns to dark. My face followed the daylight till it slowly darkened. I cannot tell who I am. My identity has disappeared. This work speaks about a family story, a spirit of family. In the middle of my forehead, the text means “Move the Mountain by Fool (Yu Kong Yi Shan)”. This traditional Chinese story is known by all common people, it is about determination and challenge. If you really want to do something, then it could really happen. Other texts are about human fate, like a kind of divination. Your eyes, nose, mouth, ears, cheekbone, and moles indicate your future, wealth, sex, disease, etc. I always feel that some mysterious fate surrounds human life which you can do nothing about, you can do nothing to control it, it just happened”.
