Platform made of 1500 beijing grey bricks and 1500 red chinese plastic stamps placed on it. Stamps have a central role in Chinese people’s life: they use them to confirm agreements and validate their actions. In a certain way loosing your stamp is like loosing your own identity. Each stamp is not carrying a name but it has been carved with a fragment of map, a group of houses, a piece of city, to mark the relationship and identification between people and their living space.
