This is a project that no one knows about.
I worked for a while at TANK Shanghai. I moved advertising papers that were hidden in places where there was no law and pasted them into the bright and shiny space of the gallery. Most of these advertisements were for illegal medical treatment, human trafficking, and drug dealing.
This project was later discovered by the museum's guards and the papers were torn down. The curator did not know at the time that I had made the advertisements, but he always thought that they had been put up by strange people who had infiltrated the gallery for a visit.
