How did they draw the meridian chart without X-rays in ancient times?

Because of shoulder and neck pain, I lie on the bed, waiting for my brother who is doing moxibustion to give me acupuncture treatment. The acupoints near the back of the neck are numb, and then moxibustion is used to draw needles. Hot air passes through the body along the needle, as if it were conducted to the waist along a thin line. I understand that the path of this hot air is meridian.

Every time I go to a beauty shop, my young sister always quotes cases such as straightening the liver meridian, losing weight and being young, and finally consumes a meridian package. My little sister's hand touched down her thigh inch by inch, making me scream. This is definitely not the pain of pressing your hand down, but the pain of being pressed by a thread. I believe this is the meridian.

Why did the ancients draw the meridian chart, but not the modern people? I understand because the research methods are different.

The study of meridians is inseparable from the study of the body. Meridian exists in the living body, and the dead can't feel it.

Modern medicine has no evidence to prove that the dead have meridians, but no one has proved that the living have no meridians, because proving that the living have meridians requires in vivo experiments, which may be life-threatening. I believe that few scientists dare to engage in such experiments openly.

In ancient China, life belonged to the emperor. Under the banner of serving the emperor, it was very easy for ancient doctors to extract several death row prisoners for living experiments. The emperor's longevity is the most important thing, and longevity comes at a price. An alchemist killed so many people, but the emperor still has to take the right path. We should study the right path. In order to improve the success rate, the emperor can give doctors too many privileges to do experiments and make contacts under the background of endless materials to practice.

Behind the meridian chart are different moral values and values between China and the West.
