But this belongs to the category of 'internal', not something all doctors can accurately diagnose.
Otherwise, there wouldn't be such a word as "quack".
But if it's relying solely on touch without using pulse diagnosis, then it becomes even more challenging.
Especially in terms of precision:
For instance, differentiating between 36.7 and 37.2 degrees—it's truly challenging for a doctor to sense this by touch alone.
Because a doctor can't guarantee their own body temperature is normal, making misdiagnosis quite likely.
In medical terms, 37.2 degrees can already be considered a sign of an elevated temperature.
It may seem fine at first glance, but the illness might erupt after nightfall.
Therefore, the 'thermometer' Xu Yun created, from a medical perspective, is as significant as chalk!
Of course.
Considering the toxicity of mercury, the widespread use of thermometers must be more tightly controlled than that of chalk.
