Units of measurement in traditional Chinese medicine. What do you mean by [one step] [Xiao Yi] and [one army]?

The unit of measurement used in ancient prescriptions of traditional Chinese medicine is the old market system, that is, 1 kg = 16 Liang, 1 Liang is 10 yuan, 1 Yuan is 10 yuan, 1 Yuan is/kloc-0. The word "bu" and "fen" mentioned in the subjective question are actually a unit of measurement, except that ancient Chinese medicine used "bu" as a symbol of "fen" instead of fen, that is to say, "bu" is a dose of Chinese medicine, which can be used as "Xia", that is, "Yi" is on it, and "bu" is in ancient Chinese medicine.
