Background: A Hakka, Kate Tsui was born and raised in Hong Kong. Her father works in logistics, and while her mother is now a homemaker, she was a dancer when she was younger. Tsui also has an older sister, who is married with two kids. As of 2014, Tsui has expressed that with the exception of herself, her entire immediate family now resides in Taiwan.
Context: 2012 is arguably Tsui's peak year in her TV career. In Highs and Lows, Tsui portrays an extremely tragic character that struggled with substance abuse, gang rape, and eventually, drug dealing. Tsui described her experience of filming this drama as "being on an emotional roller coaster", to the extent that she did not wish to speak to anyone or pick up the phone after work. The producer of the drama, Lam Chi Wah, referred to Tsui's role in Highs and Lows as the greatest breakthrough in her career and applauded her for setting down her image as a beauty pageant winner to dive into such a complex character in the drama. Film director, Patrick Kong, also noted in his column that Tsui's acting has greatly matured in Highs and Lows, particularly in her portrayal of emotional scenes.  The role at last earned her the Favourite Female Character award for the TVB Anniversary Awards 2012. Tsui was also nominated in the Best Actress category and was one of the top 5 finalists for the award. Aside from the aforementioned Hong Kong TVB-based awards show, Tsui also received a nomination for Best Actress in a Leading Role for the Asian Television Awards, which is an awards show held in Singapore that recognizes production excellence in over 15 Asian countries.  In 2014, Tsui took part in a TVB-produced micro film, A Time of Love, which consists of four individual stories, each with a separate theme. Tsui starred opposite Taiwanese actors, James Wen and Chris Wang, in the "sorrow" themed story. After the airing of the micro film, TVB received 39 individual viewer statements that commended Tsui of her outstanding performance in the micro film. Column writer, Ko Leung, of Macao Daily, also stated Tsui portrayed her character in the micro film perfectly and that Tsui's acting is comparable to that of Bai Baihe in The Stolen Years.  In 2015, Tsui's management contract with TVB ended. However, Tsui said that she is still on very good terms with TVB, and TVB has settled job arrangements for her up until February 2016. Despite having received several offers, Tsui stated that she will not finalize any management contract agreements until she has completed her jewelry design courses.
