At the geographical starting point of the earliest Great Wall of China, the Great Wall of Qin in Lintao, Gansu, I stacked walls of different shapes with bricks on the deserted ruins of the ancient wall, then pushed them down or let the wall collapse by itself.

The performance takes place at the starting point of the largest military project built by China's first emperor more than 2,000 years ago with the labour and resources of the whole country. Yet few people can find it today. Back to the beginning of all walls, back to the end of time and space, back to the time when more than two thousand years of imprisonment were about to begin, I added another absurd wall on top of the great wall. I changed the orientation of a brick. I stretched out a finger and pushed down a crumbling wall.

Since the early 21st century, the Chinese government has been building an ever-expanding Great Firewall to protect its citizens from dangerous ideas from the rest of the world. It has now grown into an almost unassailably large and complex system of technological surveillance and censorship. Unlike the ancient Great Wall, most people living behind the newly built Great Firewall are unaware of its existence and its impact on their lives.
