Play, preservation, and design as a force for positive social change are important themes in Yuyu’s work. In Hong Kong – her native city – she project managed a corporate interior renovation and three library renovations while with HIR Studio. For the library on Tsing Yi, an urban island in Hong Kong, she was instrumental in creating an ocean-inspired children’s section in which undulating shelves, a mural on a curved wall, colourful disks hovering overhead, and free-flowing, marine-hued seating all contribute to the impression of swimming through a coral reef. At HIR Studio she also designed The Ornithopter, an exercise-promoting park installation: its stationary bikes are connected to brightly painted metal wings that flap faster when riders pedal harder. Yuyu’s volunteer projects include working with an Indigenous village in the Cool Mountains of Sichuan, China, to preserve and document traditional houses and collaborating with the non-profit organization DOMAT on space-efficient, multi-purpose furniture for low-income families living in tiny flats. At PLANT she has worked on projects ranging from Toronto Community Housing renovations to the shortlisted round of the St. Lawrence Centre for the Arts International Design Competition. Yuyu passed the Professional Assessment jointly organized by Hong Kong Institute of Architects & Architects Registration Board in 2021.
