Jung began her career as a model, then made her acting breakthrough in Nobody’s Daughter Haewon (2013). In 2013, she released an EP of indie-folk songs she composed herself, the self-titled Jung Eun Chae. Jung Eun Chae spent 8 years living in London, starting from middle school senior year when she was 15-year-old.
Due to the influence of her older brother who works at a production company, Chorokbaem Media, Jung became interested in pursuing an acting career after she returned to South Korea. Jung Eun Chae debuted as a commercial model. A string of memorable commercials has earned her a CF Model of the Year title at the 2011 6th Asia Model Festival Awards. She uses a stage name instead of her real name “Jung Sol Mi” because of the similarity with a veteran actress Park Sol Mi.
