"Shape refers to the physical form, while form refers to posture. Observing the form involves diagnosing diseases by observing the patient's physical build, strength or weakness, and state of motion or stillness. This is what we commonly refer to as visual diagnosis."
Hearing the two discuss so much, Lu Xuan couldn't help but interject: "The human body is an organic whole centered around the five organs, interacting internally and externally. The strength, weakness, and movement of the body are closely related to the prosperity or decline of organ essence and qi-blood circulation.
If the internal is strong, the external will be strong; if the internal is weak, the external will be weak.
The imbalance of organ Yin and Yang, qi, and blood can manifest as abnormal forms, which can serve as the basis for diagnosing diseases. Different forms can reflect differences in constitution, indicating tendencies towards certain diseases and specific symptomatic patterns.
