[3] Cheung developed an interest in filmmaking after visiting her sisters' production sets at a young age, and became passionate about photography during secondary school.
[4][5] Cheung studied abroad in Northern Ireland from the age of 11,[4][6] and began working on her sisters' projects upon returning to Hong Kong during summer holidays since 15, which she considers valuable experience for her future in the film industry.
[11] Justin Chang described Cheung's art direction as "fastidiously grim, f/x-cluttered", resulting in a film that felt "monotonous" in his review for Variety.
[12] She continued as a production designer for Christopher Doyle's 2015 anthology film Hong Kong Trilogy: Preschooled Preoccupied Preposterous and Chapman To's 2016 comedy Let's Eat!.
[17] In the same year, she underwent another surgery for her scoliosis, which affected her ability to work continuously, prompting her to reduce her film commitments.
[25] Tara Judah of Screen Daily lauded Cheung's "colorful production design", which made the city apartment that serves as the film's sole set "feel like a lively playroom".
[27] In 2023, she served as the production designer for Nick Cheuk's directorial debut Time Still Turns the Pages,[28] which earned her a fifth nomination for Best Art Direction in the 42nd Hong Kong Film Awards.
