"One side on the ground, the other side walking on the edge. The thin body drags the truck, the petite body holds the giant tree, and thinks of herself as a superman. Until her teeth are broken, she realizes that she can't hold on anymore."

"Beside the Wall" was made on site according to the low wall on the top floor, which is about 50 meters long. The total height of the wall is 171 cm. The height of the top floor from the wall is 70 cm, and the wall thickness is 7 cm. The artist built a metal walkway with a width of 15 cm outside the top wall of the building. The performer walked along the entire wall on the unshaded roof of the top floor, which took about 55 minutes.

The performance structure matches the artist’s body size: 166 cm in height and 25 cm in length of the feet, designed to make the audience "condescending". The height difference of 100 cm in the foothold level makes the performer a lot shorter than the audience and can be precisely showing 10 cm of the top of the head, peeking the audience on the inside of the wall from the outside of the wall. At the same time, the performer stands on a foothold, and the heels are suspended for 10 cm. During the movement, only the front half of the feet support the body weight.

"Beside the Wall" is different from the obvious crisis that pervaded the previous "Floating Body" series. "Beside the Wall" hides the crisis in the details of body size and numerical value, including: the arms and palms are bent at 90 degrees to support the wall, and the heels are suspended in the air. The temperature of the 10-centimeter metal walkway and concrete wall that moves and supports in the state of stepping feet can rise to 50°C. With the hard and exhausting support of the wrist, arm, forefoot, and skin, the actor can appear relaxed, light and gentle.

In addition, the performer changes from the overhead viewing angle to the upward viewing angle lower than the audience. The audience, as the overlooker, chooses to interact with the performer in a down-to-earth position. During the process of moving among the wall, the performer randomly places peanuts on the wall, staring at the audience and waiting for the event to be triggered. The forms of audience intervention include: keeping a distance, watching from a distance, taking and eating peanuts, feeding the performer water, feeding peanuts, pouring water on the wall and metal walkways, peeling peanuts and placing the nuts on the wall, returning peanut shells, placing iced coffee, placing cigarette packs and cigarettes, peeling peanuts and hand to the performer, pick up the peanuts and move them to the back.

The wall becomes a meeting medium. The performer create a coexistence relationship between the audience and performer through the event, and promote an organic multi-directional participation relationship. Faced with the body in danger, how will the audience interact with the performer based on their existing experience?
