過時 Obsolescence exists as a personal response to the current systematic dismantling of Hong Kong and its heritage, focusing on the decay of Hong Kong's distinct cultural identity during the rapid and increasing integration with mainland China. The photobook was shot on expired film left over from Hong Kong families. Divided into three chapters, it is inspired by the structure of Banyan trees in Hong Kong, which have not changed yet.

枝 Branches, traces the origins and establishment of modern Hong Kong, from stilt houses and public housing to tea houses and Chinese pharmacies.

葉 Leaves, colour gradually shifts, like the senescence of leaves. They eventually fall to the ground, like the past, being torn away. The photographs are of remaining infrastructures and local businesses, as some have already been demolished today.

根 Roots, displays diptych photographs of fallen Bauhinia flowers, the flower on the Hong Kong flag, and everyday scenes, questioning the loss of Hong Kong’s roots and the aftermath.

The photobook is designed and handmade to resemble a Chinese tear-off calendar, which appears in various photographs throughout the book. Each page from yesterday is torn off until all pages are torn at the end of each year. In the end, only scraps of paper remain, faintly but stubbornly clinging to the spine of the book. Like afterimages of the city, fragmented.
