Considering how unusual it was in most fine homes and high-rise condominiums, or even a king's palace, to find reliable systems of refrigeration and food storage many thousands of years ago, or even a hundred years ago, it would be natural that one of the first things in both importance and in the life of a child that was sorely needed in order to protect lives and prevent violent illness was EDUCATION about「holding rancid meat」and the potential dangers of「palming maggots」as what was safe to eat, what was not. Interestingly, the pit hole dwellers held a slight advantage over the gentry with regard to food preservation, since the deepest part of a Chinese yaodong remains at consistently cool temperatures the year around due to being buried deeply in soil…which is why the rich folks all dug root cellars, by the way. No one was truly safe from the other sort of rancid meat prior to the development of antibiotics, the shaman's chanting, smoke, and mirrors notwithstanding.
　Furthermore, considering the rampant sexual behavior of humans prior to the development of religious and societal laws intended to slow down the spread of illnesses, EDUCATION about「rancid meat」of a different sort was just as essential, just as early in life. How to「control loose dripping meat」or what to do when「palming meat that is stinky」describes EDUCATING people about the symptoms and treatments for gonorrhea and other sexually transmitted diseases.
　「Child inverted」or「palming head control of loose dripping meat」as TO GIVE BIRTH TO something. And giving birth necessitated prior BREEDING with one's「dripping stinky meat」to inseminate the mother.
　「Palming loose dripping meat」as NURTURING, REARING, EDUCATING a child for a bright, happy and healthy future, demonstrating how that is done on a personal level, depicting the practice of teaching the safest sex possible to children as「palming meat」(by yourself) to prevent infection, the scourge of that day and most any other day:「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term)…. Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

Do not fool yourself into believing that this glyph started out referring to reading, writing, and arithmetic.
　RAISING MEAT FOR FOOD with early humans being unabashed cannibals, so the scholars may be correct who say these elements are「newborn meat」with that very literal meaning:「Human cannibals likely took a big bite out of their fellow humans about 10,000 years ago, according to a study that examined prehistoric bones with scratch and bite marks on them. …In the end, they discovered 30 bones belonging to three individuals: a robust adult, a gracile adult and an infant. However, the infant had only one complete bone (a shoulder blade, or scapula) that did not show signs of cannibalism, the researchers said. …But the practice goes way back: there's even evidence of Neanderthal cannibalism in Belgium and Spain from more than 40,000 years ago, when they went extinct, Live Science previously reported.」

　「We know that human sacrifice and cannibalism were widely practiced in pre-literate societies and that they were not local but universal cultural phenomena…. [T]he ancient Chinese also participated in this culture, which has much in common with the [Journal of Generative Anthropology] position about the violent origin and early development of human civilization…」
