Box therapy is a kind of psychotherapy developed in Europe, which originated from the world technique (the world technique) for child psychotherapy founded by M. Lowenfeld (1890-1973), a pediatrician in London, England, in 1929. In child counseling, Lowenfeld noticed that children could fully express the content of their inner world in play, and when given toys, models and sandboxes children made interesting works that could provide positive help for psychotherapy. She named this method “The World Techique” and published her thesis in 1939. The “world” is said to be a natural word for children, and for them, this play therapy may in some way reflect their “world”. The Swiss psychotherapist Dora M. Kalff developed Lauenfeld’s world technique and named it sandspiel to distinguish it from Lauenfeld’s world technique. Kawai Hayao named it Hakodan Therapy when he introduced it to Japan. Since 1965, this “world technique” has been used for counseling and treatment at Tenri University, Kyoto City Counseling Center, and the Psycho-Educational Counseling Office of the Faculty of Education of Kyoto University, and has achieved excellent therapeutic and counseling results. With the development of clinical psychological theory and practice, more and more psychologists have begun to pay attention to box therapy and have combined it with Jungian analytical psychology and related theories to enrich and develop this therapy. Currently, the United States and Japan are leading the way in the development of box court therapy, whether in terms of theoretical construction or related therapeutic techniques and training of professional therapists. Although China started late in this area, and it was only introduced to China in the 1990s. However, there are already a group of pioneers in the world of box room who are working tirelessly in this happy land. Ms. Sakurai Soko, a Japanese expert in box therapy and a commissioned counselor of the Psycho-Educational Counseling Office of Kyoto University, has come to China many times to introduce box therapy to relevant parties, and made a special presentation at the “Hubei Women’s and Children’s Health Care Symposium” in 1997. It attracted a lot of interest from the participants and was highly evaluated. Box therapy is a kind of psychotherapy in which visitors freely select toys from the toy shelf and perform self-expression in a special sand box filled with fine sand in the company of the therapist. As a kind of psychotherapy, box therapy has been well developed in terms of its theory, techniques, and case studies. Compared with other counseling therapies, box therapy gives more non-verbal and symbolic level support to the patient, which is easier to penetrate into the unconscious of the counselor, more able to gain insight into the psychological trajectory of the client, release and express their inner emotions, and allow the deeper personality of the client to be expressed. At the same time, it also allows the counselor’s own stress to be released.
