She was eliminated in the round of 16.[4] She later attended Hong Kong Baptist University in 2014 and featured as a background actor in Heiward Mak's 2014 romance film Uncertain Relationship Society [zh].[2] However, as her grades in freshman year did not meet the requirements for a film major, she chose to pursue a financial journalism major instead. Nevertheless, her passion for films persisted and she even set her graduation thesis topic related to the development of creative media.[2] She had also attended lyrics writing classes taught by Chow Yiu-fai [zh] during her university years.[1] After graduating with a Bachelor of Communication, she joined Commercial Radio Hong Kong as a production assistant of ILUB [zh]'s program.[2] In 2019, she began to host her own late night program.[4] However, she quitted the job in early 2020 to pursue a longed-for acting career.[2][4] Besides, Chung also started her lyricist career under the pen name "Chung Said" (鍾說) in late 2019 and wrote Jace Chan's "Born to Be Different [zh]", Janice Vidal's "Little Miss Janice" and Joey Hung [zh]'s "Dirty".[5]
Chung landed her first onscreen role in 2019 ViuTV drama series Limited Education [zh] and received public attention.[2][6] Wong Chi-yeung, the director and writer of the series, offered her the role without casting as Chung left him with a deep impression while auditioning for the 2016 drama film Weeds on Fire.[6] In 2021, Chung was cast in lead role in the black comedy film Time, portraying an orphaned schoolgirl who forms an uncanny bonding with a retired assassin.[7] She received nominations for Best New Performer and Best Supporting Actress in the 40th Hong Kong Film Awards with her performance.[8] From 2021 to 2022, she also featured in lead roles in the biographical film Zero to Hero, sports film Life Must Go On [zh] and horror thriller Let It Ghost [zh].[9]
