This paper investigates the traits of a successful EFL teacher at a Chinese University by collecting qualitative data, including surveys with questionnaires and interviews, from Miss H and a group of her students and her colleagues. The purpose is to detect what special qualities she has and what other roles she undertakes in her teaching position. The data indicate that to fulfil her role as both a teacher and a "tour guide", Miss H has the qualities of being knowledgeable, responsible, enthusiastic, patient and kind. She also has a strong ability to utilise her teaching methods in accordance with what her students need and to train them to learn in a communicative and independent way. She serves as both a friend to her students, giving them support and helping them with learning, and as a coordinator among her colleagues, encouraging professional development and cooperative teamwork.
