BEIJING (Web Desk) – Chinese artist Liu Bolin, an expert in disappearing act, has released a series of decade old works, “Hiding in the City”, reported CNN.

Liu has continued to work within the unique medium – camouflaging himself into various backgrounds with the aim of raising awareness on political and societal issues.

“I always use my works to question and rethink the inequality and imbalance caused by the process of human development,” says Liu, who in the past, has been painted to ‘disappear’ into the backdrop of demolition sites and supermarket aisles.

Chinese artist Liu Bolin is a master of disguise. Over the past decade he's highlighted some of the world's most pressing issues with his work.

In China, it's a common sight to see advertisements like these plastered on walls. Liu has to stand, patiently for hours at a time, while his assistants paint him to match a chosen backdrop. <br />

In recent years, Liu's works have touched upon modern day technologies -- which he finds worrying. "In the modern era, everyone is just a piece of data, which is valued less and less everyday. Meanwhile technologies achieved by desire, or the possibilities of some sort of human development, is winning over the hearts of modern day people."

"After these 10 years of my creative career—as far as I come—when I'm creating a work, or just viewing one, or just trying to express my idea as an artist, the most important part about the work is my attitude towards reality," Liu says.

Liu Bolin collaborated with French street artist JR on this work. Liu hides himself in one of JR's large-scale murals in New York City.<br />

This mural, which conceals both Liu Bolin and Bon Jovi, became the album cover for Bon Jovi's What About Now. The background mural was designed by Alex Haldi.<br />

"When I pick a background and disappear, I've already expressed my attitude towards society, the future, and desire. It's a deep understanding that I bring to the audience," Liu says.<br />

Liu has travelled the world for exhibitions. He has 'hid' in cities around the world. Of his progression, Liu says, "I think the imbalance of human development is embodied more and more in my works."<br />

“Disappearing is not the main point of my work,” Liu says. “It’s just the method I use to pass on a message. To tell people if we don’t stop the way we live, or pay attention, we will all face our own disasters. It’s my way to convey all the anxiety I feel for human beings.”
