Answer:
When treating a disease, doctors of TCM usually find the patient's condition through these four diagnostic methods: observation, auscultation and olfaction, interrogation, pulse, and palpation.
MEANINGS ;-
"Observation" means looking at the appearance and tongue fur, "auscultation and olfaction" refers to listening to the sound of the patient's speech and breath, "interrogation" refers to asking about the patient's symptoms, and "pulse-feeling and palpation" is just in the literal meaning.
