Television
In 2005, Chen began her professional acting career when she signed an 8-year contract with TVB. She started out as a host on numerous variety shows on TVB's Mandarin channel TVB8, before making her acting debut in the TVB series Forensic Heroes guest starring as a murderess.
In 2007, after starring in Heart of Greed, The Family Link, and Steps, Chen won her first acting award in the Best Supporting Actress category for her role in Steps. Additionally, she was also nominated for "My Favorite Female Character" and "Most Improved Actress" categories for the same role. She also received a nomination in the "Most Improved Actress" category for her roles in Heart of Greed and The Family Link in 2007.
Chen's breakthrough came in 2008, when her notable work was for the character of Gam Wing Hing (a mute girl) in TVB series Moonlight Resonance, an indirect sequel to Heart of Greed, as she had to learn sign language for the role. The role landed her nominations in the "Best Supporting Actress" and "My Favorite Female Character" categories for the second year in a row.
In 2009, Chen was nominated again for the "Best Supporting Actress" and "My Favorite Female Character" categories for her role in The Stew of Life.
In 2010, Chen was cast in TVB's grand production series No Regrets as second female lead, securing her position as one of Hong Kong's celebrated new actresses, alongside Tavia Yeung, Linda Chung, Myolie Wu, and Kate Tsui. The role won her the Best Supporting Actress Award at the TVB Anniversary Awards and Best Actress in a Supporting Role at the 16th Asian Television Awards.
She later took on roles as the first female lead in productions including Lives of Omission, Queens of Diamonds and Hearts, and Triumph in the Skies II. Lives of Omission (2011) was a distant sequel to the 2009 film Turning Point in which Chen had also acted in as the sister of a triad boss. Queens of Diamonds and Hearts (2012) allowed Chen to experiment with looking 'ugly' on screen as her character Chung Mo Yim, based on historical figure Zhongli Chun, was born with a prominent birth mark on her face. Chen played the role of Holiday Ho in Triumph in the Skies II —a free-spirited punk girl who aspires to fly—who became emotionally entangled between two male leads, Captain Samuel Tong played by Francis Ng and Captain Jayden Koo played by Julian Cheung. Chen also starred in 2013's Will Power alongside veteran actors Wayne Lai and Moses Chan where she played the role of Sam Yuet Kan, a junior barrister with a tough personality.
Her contract with TVB ended in mid 2013 and Chen became a self-managed artiste.
Chen acted in her first mainland Chinese drama series, Sound of the Desert, where she played the role of Li Yan. It aired in 2014 and was based on the historical romance novel Ballad of the Desert by Tong Hua.
Shortly after graduating from the Juilliard School, Chen was cast as Jolene in The Undoing alongside Nicole Kidman and Hugh Grant.
