Background: 1995, a group of freelance artists from Beijing's "East Village" jointly created "The Unknown Mountain is one meter high", which not only became a classic of contemporary performance art in China, but also left a colorful stroke in the history of photography in China. 1 1 Naked men and women are "naked" from bottom to top with numbers of 3, 2, 2, 2, 1 in a strange and full of dialectical tension, with the heaviest person lying on the bottom and the lightest person lying on it, with a height of 1 meter. Standing on the next nameless mountain top, people, people and nature, men and women are re-placed in the dimension of love and mercy to explore the original existence relationship, giving people an unprecedented "China experience" of body art.

1999 "The Unknown Mountain is one meter high" participated in the 48th Venice International Biennale, which was a sensation.

The young artists who participated in it at that time have now become famous heavyweights, including: Cang Xin, Zu Mantra, Ma Zongyin, Zhang Huan, Ma, Wen and Duan. Of course, there is the photographer, a famous photographer who keeps a low profile-Lv Nan.
