1. Attach importance to theory and explore concealment. From the first classic of acupuncture to the Song Dynasty, more attention was paid to the textual research of acupoints and the excavation of new acupoints (namely Ashi acupoint), but there was no great development in theory, as the Preface of Meridian Liuzhu Needle Classics said: "In modern times, there are many people who refer to stab diseases, but there are also many people who do not follow the rules." Acupuncture theory is expounded and innovated according to the theories of Neijing and Difficult Classic. Especially in the aspects of manipulation and acupoint selection, it is deeply discussed and recorded in the form of songs, which is not only convenient for clinical application, but also conducive to learning and memory. 2. reply to the appointment through Bo and use the points accurately. The requirement of sinus is "take five points, use one point, but it must end;" Take three classics to make them correct. "Determine the origin 12 as the fulcrum, and Liu Zhudian 8 as the contour discipline. Therefore, when selecting acupoints, doctors should keep it simple and complicated. 3. Pay attention to techniques and highlight qi activity. Acupuncture manipulation directly affects the effect of acupuncture treatment. In clinical acupuncture, it is difficult to achieve the expected clinical effect if we only pay attention to acupoint selection and ignore manipulation. Dou's outstanding academic thought is to attach importance to acupuncture and advocate "micro-needle connected with wonderful needle", in which "wonderful needle" means proper pointer method. Before the Tang Dynasty, more attention was paid to the study of acupoints, but less to acupuncture. This is because doctors do not pay enough attention to the theoretical essence of acupuncture technology in Neijing. However, Dou clearly put forward "the method of saving the world, using acupuncture skillfully", and thought that the key to nourishing yin and blood by acupuncture was manipulation, and the key to manipulation was skillful luck. When qi is accessible, Yin and Yang qi and blood can be regulated, viscera and meridians can be unblocked, and qi stagnation can be eliminated. In this regard, the Dou family left us a well-known wisdom saying: "Go with it and slow it down, and the future will be slow, but it will be heavy and tight", "Those who stab it will make this God move backwards; It also makes this person calm. Paying attention to the combination of "meaning" and "qi" plays an important role in improving the curative effect of acupuncture. 4. Emphasize the overall idea of the unity of man and nature. Meridian Liu Zhu is a classic acupuncture method in the acupuncture discipline of the motherland, which pays attention to adapting to the times. It is based on the internal and external unified holistic view of "heaven and man are also related, and the sun and the moon correspond" in Neijing, and the theory of combining rigidity and softness with yin and yang and five elements. According to the changing law of heavenly stems and earthly branches, the opening and closing time of human qi and blood circulation in the meridians is calculated, so that the five elements and five Shu points are selected and the best acupuncture method is obtained by acupuncture reinforcing and reducing. Dou summarized the acupuncture methods of meridians, and put forward the method of eight pulses and eight points, which laid the foundation for the eight methods formed in later generations, and clearly put forward the theory of "controlling time by acupoints" for the first time in the eight methods. Dou's academic thought has a far-reaching influence on later generations. Based on the theory and works of Dou, the master of acupuncture and moxibustion formed such a famous acupuncture and moxibustion work.
