The pulse is deep, thin, and weak, and the tongue is pale and lacking luster.
The pulse being deep, thin, and weak indicates a deficiency in the body's qi and blood.
The deep pulse refers to a low pulse position that cannot be felt with light pressure and only felt with heavy pressure.
The thin pulse is as slender as a thread but is clearly felt.
The weak pulse is characterized by being deep, thin, soft, and lacking strength.
Whether it is a deep pulse, a thin pulse, or a weak pulse, all three indicate that the patient has a deficiency in qi and blood.
If the patient has a deficiency in qi and blood, especially after the spleen qi is weak, it will lead to insufficient generation of the qi and blood, causing the blood to be unable to fill the vessels, resulting in a deep, thin, and weak pulse.
Patients with such a pulse may experience general fatigue in daily life or have inherently weak and many diseases.
Old Zhou's situation undoubtedly confirms this point.
