Sandplay is also called sandplay. Sandplay therapy is a very popular psychotherapy method in the world. It is widely used in children's psychological education and psychotherapy in schools and kindergartens; It is also very popular in universities and adult psychological clinics. By arousing childlike innocence, people can find a way to return to their hearts, and then problems such as physical and mental disorders, social maladjustment and personality development obstacles can be solved in the sand table. Sandplay can be used for children and adults; It can be done by individuals alone, or by families or other forms of groups; Visitors can freely complete the sand table, or make a theme sand table according to a certain theme. Each way has its own special procedures, but they all follow the unconscious working mode of accommodation, protection and freedom. Their fundamental purpose and healing principle is to contact the unconscious through the process of sand table game, so as to achieve the purpose of spiritual development and transformation. The process of sand table therapy includes several steps: first, introduce the use of sand and water in sand table to visitors, and introduce the types and placement positions of various molds, so that visitors can feel safe and free and understand that they have sufficient conditions to choose any mold for any form of creation. Then the therapist helps visitors create a sandbox world with a spontaneous game mentality, and freely express their inner feelings, which is the arousal of "childlike innocence" mentioned above. Once the visitor can place the sand table with such childlike innocence, he begins to explore himself with the help of the sand table. Next, visitors began to build a sand table world. At this time, the principle of "nonverbal therapy" was followed. Therapists try to keep a protective and accompanying observation and record, and try to let visitors communicate with the sand table themselves. After placing the sand table, the therapist began to accompany the visitors to explore the sand table world, trying to deeply experience the sand table world, giving them a feeling of * * * in appropriate places, and giving suggestive, metaphorical or questioning explanations when necessary. After these processes are completed, taking photos of the sand table world aims to record the whole sand table game treatment process and also to commemorate the mental journey. Sandplay therapy emphasizes non-language and non-explanation, and pays attention to experience and experience. However, as a therapeutic method of psychoanalysis, sandbox game still works on the unconscious level, which determines that sandbox game uses symbolic expression. Therefore, to understand the information of sand table, we must learn this unconscious "language". In the treatment, the therapist will not make a clear symbolic explanation or comment on the visitors, but this symbolic understanding is an important clue to guide the therapist's work. However, it is not enough to learn symbols in this way. Therapists themselves have to go through personal sandbox game therapy for quite some time, aiming at experiencing the unconscious level attached to each symbol in their own experience, that is to say, really understanding these molds and sand tools and establishing material and spiritual ties with them. This is also the basic setting of "childlike innocence" mentioned above. Only by doing these preliminary work well can the therapist complete a sandbox and truly give it the meaning of the door of the unconscious. Sandplay is a means of psychological counseling, and it is also a method of psychotherapy and psychological counseling by using sand, sand table and miniature models of people or things. In a free and protected space, visitors can touch the unconscious and express their super-language experience and blocked energy by playing with various models and toys in the sand table. This kind of contact and expression can promote the power of activation, recovery, transformation, healing and rebirth, and promote the maintenance of mental health, the cultivation of imagination and creativity, the development of personality and the growth of mind of visitors. Emphasizing the spontaneity and autonomy of the creative process itself is the basic feature of sandplay therapy, and making full use of nonverbal communication and symbolic meaning is the essential feature of sandplay therapy. In addition, the basic principle of this therapy is to give people the freedom of imagination to the maximum extent, so that people can carefully construct and develop various themes that can gallop freely in their minds. It has become one of the most mature and effective treatment methods abroad, widely used in psychoanalysis, psychotherapy and related psychological education, and has formed a group of professional sand table psychotherapists. As a therapeutic method, sand play was inspired by Jung's positive imagination technology and theory, and finally came into being and came out in the 1960s through the continuous efforts of winfield and Dora Calve, the inspiration of ancient traditions and the spontaneous expression of children's nature. At first, its treatment object was mainly children, and now it is gradually extended to psychological analysis and treatment of adults. Sandplay has two basic elements: sand and miniature models of people or things. Sand is one of children's favorite materials. Almost everyone has had the experience of playing with sand in childhood, and children in different countries and different periods are almost no exception. The fluidity and plasticity of sand enable people to use their imagination at will, and they can use it to build castles, villages, mountains, rivers and anything else in their hearts. Because sand grains are formed by the weathering of rocks on the earth's surface, sand is also considered as an ideal material for pouring and shaping the image symbolizing the world. Blake wrote in Song of Innocence that we can "see the whole world from a grain of sand". The practice of sandplay therapy has developed rapidly in the decades since sandplay came into being. In addition to the increasing number and types of available miniature models, the object of sandplay therapy has gradually shifted from children to adults, from patients to all normal people. In addition, sandplay therapists are becoming more and more interested in the value of ancient symbols in sandplay. These symbols include gods and goddesses, creatures in the wilderness and legends about heroes. Their value to sand table therapists lies in that they can gain more in-depth knowledge about the treatment process by recognizing that there is some connection between the images and symbols of sand table scenery and the prototypes in the ancient world. It can be seen that the process of sand table therapy not only touches the core of our emotions, that is, psychological complex, but also touches the unfathomable collective unconscious field, that is, various psychological prototypes. Therefore, sandplay therapy itself can not only play the role of psychological diagnosis and treatment, but also play the role of psychological counseling and education. The application of sandplay and its therapy in normal education, especially in the education of imagination and creativity, is considered as a new development of sandplay therapy.
