The character was created by series producer Shonda Rhimes, and is portrayed by actress Sandra Oh. Introduced as a surgical intern at the fictional Seattle Grace Hospital, Yang worked her way up to resident level, eventually becoming a cardiothoracic surgical fellow, while her relationships with colleagues Meredith Grey (Ellen Pompeo), George O'Malley (T. R. Knight), Izzie Stevens (Katherine Heigl), and Alex Karev (Justin Chambers) formed a focal point of the series. Yang earlier in the series got engaged to Preston Burke (Isaiah Washington), in the past had a relationship with renowned surgeon and mentor Colin Marlow, and wed but later divorced Owen Hunt (Kevin McKidd). Oh originally auditioned for the role of Miranda Bailey, although Chandra Wilson was ultimately cast in the part. Oh has received generally positive reviews for her portrayal, with Mark Perigard of the Boston Herald considering her friendship with Meredith to be "the secret core of Grey's". Oh has also garnered numerous awards and nominations for her role as Yang, including Golden Globe and Screen Actors Guild Award wins in 2006. She was additionally nominated for the Primetime Emmy Award for Outstanding Supporting Actress in a Drama Series each year, from 2005 to 2009. Characterizing the character, ABC noted her competitiveness, ambition, and intelligence as her main traits, while her aggressive, and tactless attitude was highlighted as her main weakness. In May 2012, E! Online reported that Oh had signed on for two more years, along with her fellow cast members. Oh left the show after season 10, and her character Cristina Yang was written out of the storyline as a main cast member
