Mass recruiting so many people at once turned training into a major issue. Teaching staff could only be drawn from the military, and their qualifications weren't even considered.
The selection criteria of 'easy entry, strict exit' doomed the training to be extensive. Beyond teaching the fundamentals of Cultivation Methods and sharing experience, there was no need to trouble oneself with educating a bunch of roughnecks about imparting doctrines, imparting knowledge, and solving doubts.
It wasn't only military officers of serfs' sons and daughters with limited education, even officers from lesser noble families didn't have much higher levels of learning.
In a situation with limited resources, many families of lesser nobility focused on training only their eldest sons, while the others received only the most basic education.
