Chronopuncture is traditionally considered one of the most difficult sections of acupuncture, which has a very high entry threshold: in addition to knowing the basics of acupuncture directly, a doctor is required to have a deep knowledge of the basics of the calendar system of ancient China, a virtuoso ability to calculate trunks and branches, an understanding of the essence of the modern calculus of time and some basics of celestial mechanics. However, having learned to calculate time and build tables of open points, most specialists are faced with the fact that, often built with such difficulty, tables do not work properly.
