China's traditional diagnostic technology first came from.

China's traditional diagnostic techniques of seeing, hearing and asking originated from Bian Que, a famous doctor in the Spring and Autumn Period and the Warring States Period.

Looking, smelling, asking and feeling are the four basic methods of TCM diagnosis. According to historical records, the ancient diagnostic technique of "looking, smelling, asking and feeling" originated from Huangdi Neijing. This classic is one of the important works of traditional Chinese medicine. Written around the 2nd century BC, it is a landmark work in the medical history of China.

Wen Wen is the second step of TCM diagnosis. By listening to the patient's self-report, asking about his condition, and smelling the changes of his smell, breathing and excreta, the diagnosis and cause can be further determined. For example, symptoms such as sore throat, thirst and cough need to be further judged by asking and smelling.

The third step of TCM diagnosis is to palpate the patient's body surface with hands or instruments to check the changes of pulse, abdomen, chest and other parts, so as to judge the severity and etiology and pathogenesis of the disease. For example, in the diagnosis of diabetes in Chinese medicine, it is often necessary to judge the change of the condition by taking the pulse, touching the abdomen, back and other parts.

The application of listening, listening and asking;

1, the application of seeing, listening and asking in modern medicine.

Traditional diagnostic methods of Chinese medicine, such as looking, smelling, asking and feeling, have also been applied to modern medicine. By looking, smelling, asking and palpating, we can better understand the patient's condition and physical condition, and improve the accuracy of diagnosis and the effect of treatment. For example, neuroscience research in modern medicine shows that people's complexion and fundus reflex can reflect the state of people's nerves.

2. The application of listening, speaking and asking in different medical fields.

Besides Chinese medicine, seeing, listening and asking questions can also be applied to other medical fields. For example, in the field of western medicine, ECG, blood pressure, blood oxygen saturation and other instruments can also be regarded as a kind of "pulse diagnosis". Through technical means, the physiological indexes of patients are observed and measured to judge the condition.

3. Innovation of modern medicine.

Such as using computer technology to analyze the patient's facial expression, voice, intonation and so on. To judge the condition and type of disease. This new application provides doctors with more information and diagnostic tools, which is helpful to improve the accuracy and efficiency of medical diagnosis.
