In Pataauw Stone (Witch's Stone) Yu Ji alludes to indigenous Taiwanese lore and the early history of sulphur mining in the cultural and natural environment of Beitou. Demonstrating an extraordinary feat of physical labour and endurance, Yu Ji drags Ta Jama (Beitou Stone), a sculpture completed in Guandu, through dense wilderness, narrow mud-slopes, spiky grass, and bamboo forests, in search of a water source; ascending the mountainous terrain to find the dried marsh where she at last departs from her subject. We witness a growing bond between the object and its maker in this arduous journey and feel both the stone and the artist being imbibed with the significance and spiritual residues of such a feat. The video is interspersed with clips of stray dogs chasing one another on Xiao Youkeng, Sulfur Valley, footage of geothermal eruptions, and people soaking their feet in hot springs. The field recordings and environmental sounds of winds, drums, dogs barking and birds chirping, converge with the human voice of struggle and toil and we are able to hear three meaningful dialects in the video: Taiwanese, Mandarin, and Shanghainese. The video culminates with us witnessing the final resting place of the stone. In a lush outcrop, it is placed among a formation of other rocks, and the artist's ritual is complete. Unexpectedly, the sky thunders and the heavens open to the rain, the mountain appearing to bear witness to the artist's transformative ritual.
