"Imaginary Boundary" (2019) is a work originally commissioned by the Lung Fu Shan Environmental Center in Hong Kong as part of the exhibition ‘The Pulse of Nature’. Chan was invited to research and engage with the natural surroundings and re-live the memories of the old bungalow surrounded by the city and the mountains. The work is comprised of found concrete-coated foam packaging, which contains a dried plant pod, pebbles, ceramic tiles, and a domestic household mirror. Each element inside the sculpture directly draws on the ‘footprints’ left by the morning walkers along the Lung Fu Shan Hiking Trail. This community of walkers has gathered since the 1980s to socialize and exercise on pebbled reflexology paths, collect water from the gullies, drink tea, and grow Chinese herbs. Chan read an article from 2007 in the South China Morning Post reporting that one of the original boundary stones placed along the paths that were erected by the Hong Kong Government in 1903, went missing. This specific stone, numbered ‘7’, was erected to mark the boundary of the City of Victoria, the de facto Capital of Hong Kong during the British colonial period. Chan’s reinterpretation of the missing stone in her work "Imaginary Boundary" is an image created purely from her memory of the boundary stone at Hatton Road in Lung Fu Shan. Much like the fate of the missing stone, which was overlooked, the traces of the morning walkers appear and disappear within the sculpture: the surrounding green foliage and the otherwise invisible inscription of the number ‘7’ materialize and dissolve in the mirrored image, depending on the angle from which it is viewed. These traces present a blurry vision of contemporary Hong Kong’s relationship between the natural and artificial, past and present, public and private, and the internal and external hybrids of everyday life.
