This article reports a case in which the Yikong skill(Technique of moving symptom-images into nothingness)was applied to deal with obsessive thinking of a middle school boy. With the application of the Yikong skill, the therapist allayed the client’s obsessive thinking by directly eliminating his negative physical and mental feelings in the most easily triggered scenarios. There were four times of this treatment: the therapist collected the client’s information and evaluated his symptoms in the first time, then separately focused on two of the most easily triggered situations in the next two times, and the client had no obsessive ideas about his exams in the fourth time. Managing the obsessive thinking with the combination of Yikong skill and reflection turned out to have a quick and long-lasting effect. This paper discusses how the therapist can lead the client to find out the negative psychosomatic feelings in the situations with obsessive thinking triggered and identify the target symptoms of the Yikong skill.
