「Extreme meat」: external source Chinese sources list meanings as CULTIVATE, REFINE, and TEACHER COMPENSATION. Some say that likely the right element formerly was「raw flesh meat, butcher」(肴, 倄) to render this glyph as「person with rod in raw meat」as a TEACHER, and frankly that explanation seems to better fit with all other glyphs.「Extreme meat」as the TEACHER of many students may have been payment enough, and garnered many volunteers as tutors…remember what the course subject was at the time: see 校 meaning 'school.' Also likely is that「extreme range with meat」or「person with reciprocating motion of rod forcing meat」as an 'all-in' status…either way,「extreme meat」would be the best to use training students, and, would soon become MEAT FULLY DRAINED OF FLUIDS,「meat relaxed at ease」and shriveled some, hence the apparent association both with the reward teachers received for doing that work and so-called 'dried meat.' See 干, 乹, 凅, 乾, 涸, 萎, 脯, 槁, 䐤 and so on for「meat with no fluids」and also 滫 a Used-in glyph meaning 'insipid, diluted' as the result of a hard day's night:「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　Scholars say that「extreme range, far distant」with「meat」referred to literal strips of meat as payment for teacher services in order to keep teachers distant from butchering his own, yet the support for this idea seems to have evolved solely from interpretation of this very glyph (see https://www.chinahighlights.com/travelguide/ancient-education.htm 2017-04-20 )
　The ory suggests that receiving this「at-ease meat」meant that the recipient did not need to prepare his own meat, and did not need to raise a hand to slaughter an animal. They say that dried meat was provided to schoolteachers as payment for services, because it was better not having a butchering-type of person teaching your children when patience ran thin, and that this policy helped the teachers to maintain a calmer demeanor while teaching by not having recent practice of hacking an animal to its ultimate and bloody death, cutting out its entrails and brains, seeing pools of blood, and so on.
