Meticulous examination of each pulse represents a fixed standard. Adapting flexibly according to the individual embodies the application of a versatile and dynamic diagnostic approach. For instance, determining exterior or interior, cold or heat patterns based on floating (Fu), sinking (Chen), slow (Chi), and rapid (Shu) pulses is as natural as a shadow following its form; what is there to debate? However, since human bodies vary in shape and constitution, the arrival and departure of pulses also differ accordingly. One cannot rigidly adhere to a single theory to generalize all clinical conditions. Why is this? In individuals who are obese and robust, Qi resides at the surface, so the six positions of the pulse often present with floating (superficial) and surging (Hong) characteristics. In individuals who are thin and small, Qi is gathered within, so the six positions of the pulse often present with sinking (deep) and rapid (Shu) characteristics. For those with an impatient temperament, five beats per breath cycle constitute a normal pulse; for those with a leisurely temperament, four beats per breath cycle may indicate a heat pattern. For tall individuals, finger placement during palpation should be spaced widely; for short individuals, finger placement should be close together. People from northern regions often exhibit strong and solid pulses; people from southern regions often exhibit weak and soft pulses. The pulses of young and vigorous adults tend to be large; the pulses of the elderly tend to be deficient. Pulses after drunkenness are often rapid; pulses after drinking alcohol are often surging. Unmarried women and nuns often have soggy (Ru) and weak pulses. Infants' pulses often beat seven times per breath cycle. Thus, the classics state: "When form and Qi are harmonious, life prevails; when they are discordant by three, five, or other irregular intervals, death ensues." How can one fail to examine this carefully!

Furthermore, there is another aspect to consider: Although it is said that in obese individuals Qi resides at the surface and floating/surging pulses are their norm, if the muscles are excessively firm and dense, the pulse energy may not reach the skin surface directly but rather requires deep pressure to be felt. If one strictly adheres to the notion that floating/surging pulses are easily seen and uses only light touch, the subtle and fine original pulse characteristics will remain undetectable. Conversely, although it is said that in thin individuals Qi is gathered internally and sinking/rapid pulses are their norm, if the muscles are excessively shallow and thin, the pulse energy will manifest immediately between the skin layers, allowing knowledge of the pulse through superficial palpation (floating extraction). For impatient individuals, a rapid pulse is normal, yet in moments of calm and leisure, the pulse may appear relaxed and slow; for leisurely individuals, a slow pulse is normal, yet in moments of busyness and complexity, the pulse may become rapid and hurried. A strong pulse in northerners is normal, but those whose ancestors consumed rich foods for generations, or whose mothers were born in the south, may not necessarily lack a weak pulse presentation; a weak pulse in southerners is normal, but those with sufficient congenital endowment or accustomed to hard labor may occasionally exhibit strong and solid pulse characteristics. A large pulse in the young and vigorous is normal, but those with premature deaths often show deficient and fine pulses; a deficient pulse in the elderly is normal, but centenarians often exhibit deep and solid pulses. Soggy and weak pulses in unmarried women and nuns are normal, but those with leisurely circumstances and tranquil minds may present with a balanced and harmonious pulse. Infants possess pure Yang Qi, making rapid pulses normal; however, those with weak constitutions and cold tendencies may present with slow and delayed pulses. By extrapolating from these examples, while every person has a certain inherent form and Qi, within this form and Qi, one must account for shifts due to geographical environment to fully grasp the subtleties beyond the literal text.
