During the one-child policy era in China, many parents tried to hide their “over-born” children to avoid the administrative fine, so these children did not have the social identity necessary to go to school, find a formal job, or even buy a train ticket. They became “invisible” to society. According to China’s latest population census, conducted in 2010, there were 13 million unregistered citizens. I want people to pay attention to these “invisible children” and try to give them a chance in life. It was not their personal choices to be without a social identity. In this project, the installation on the brooch helps to hide the little “invisible child” figure inside the dark box; a photosensor will turn the interior light on when the work is shaded, or the wearer walks into the dark. The “invisible children” can then be seen. At the same time, an infinity mirror effect will be shown behind the figure. The work depicts the social status of “invisible children,” which it is not limited to isolated cases; an uncountable number of people are facing the same issue.
