This article reports a case study of the application of Yikong Skill in the intervention of a client who had suicidal thoughts over a long period and witnessed the remains of a close friend diving into suicide during the epidemic. After the initial interview, the client's "left lung distended pain", "heart tingling pain" and "fear" were treated for three times. The effect of Yikong Skill was significant: after two times of Yikong Skill treatment, the client expressed "no thought of dying" and "want to live quietly and long". After four months, the client's symptoms mentioned above disappeared and she was able to accept the death of her friend and work happily without distractions. This paper also discusses the effectiveness of Yikong Skill in improving consultants' competence.
