"Take a good shot, this is our work!" The young man who was making the barricade shouted at me briefly as he prepared to escape. The Hong Kong demonstration started in 2019. The participants left a huge number of "works", which were road obstacles made up of everything that exists in the city life. It was installed everywhere from the main streets to the back alleys and into the campus of the university, blocking the arteries of the city and stopping the enemies. All obstacles were quickly and forcibly removed by the Hong Kong Police and others, but the protesters continued to make them over and over again. It seemed to be a new attempt to regain and release the city with their own hands not only to stop the economic activity and to prevent the invasion of armed police, but also to reconstruct their city "Hong Kong", which has been high-pressured by over-expanded capitalism and the political power. I was fascinated by the "works of unknown artists" that suddenly appeared on the street, and above all, the strong resistance spirit in them. So I was absorbed in filming them. In order for the unknown artists who continued to resist, to leave a proof that they certainly existed there.
