In the winter of 2017, a fire in a Beijing temporary village let to hundreds of thousands of people forced out of the area within one week. The village committee had an overnight meeting to replace the foam steel roofs with asbestos tiles. And soon, the replacement radiated to the surrounding villages that had latent hazards. In the following months, the trucks on the street were filled with white foam steel roofs, and the workers were busy replacing the roof tiles day in and day out. In front of Tan Yingjie's studio, a pile of foam sheets amounts to tens of meters long. Whenever vehicles passed, a cloud of foam flies in the air. Like snowflakes, it stuck on people's jacket, at street corners, scattered in the dried bushes. His home also underwent roof replacement, where the foam was seen everywhere inside. Before the roof was properly re-installed, the workers were forced out of the city, leaving gaping roof open for two weeks.

For this exhibition, Tan Yingjie adopted the story "Snake Fog" from Branches of the Allegorical Forest, and compares the viewers to the people of the Underworld Valley, with which to inquire into the reasons why people have came to live in the circumstances where justice could not be sought out? He compares the space as "Fog Valley" and divides it into three parts: the main space is filled with ten pieces of large foams from rooftop sheets, where paintings, sculptures, videos and multimedia works of art are nestled in the forest of "fog valley"; the second floor space is enwrapped with foam bubble pads, on the roof, floor, staircase and handles, into an enclosed space that is both safe and dangerous; and the lower tier floor consists of black liquid and photographs.

Amongst the warm yet fragile foams, one's reluctant experience may be precarious. Just like the unshakable grains of foam in "Linger". This sense of living the consequences of one's own action can also be traced in the video of a performance, "A White Explosion", documenting an explosion incident that occurred two years ago. The integrated conflicts in the forest of fog valley come from the contradictory relationships among all people in the current social environment. For an individual, the common solution is to withhold one's rights and desires, so the conflicts would disappear, like those in "Snake Fog", who would rather inhale heavy air to their death than confronting the reality.
