Beside this, I believe that the earlier they systematise their bureaucratic records-keeping, the more it will look like a Qin bureaucracy with all the elitism that it entailed, and hence the more that they will be compelled to find ways in making their literature somewhat abstruse.The alphabet is something I’ve actually been thinking about. For Misian in particular, I’ve noticed that the language has a certain syllable structure that would lend it to a syllabary or abjad-type system. I’ve also been thinking about the Korean writing system, in which sounds share shapes based on how similar they are and how they are said. For example, the three main plosives in this language (at least in the Inoka dialect) are P, T, and K. I’m thinking they can be represented by the symbols Γ, T, and 7 respectively, representing the position of lips/tongue with relation to the roof of the mouth.
That said - in order to answer this question - you may as well answer how they did their enfeoffment of land and noble entitlements in the earlier time periods, and how it coupled along with the centralisation that the extensive canal system had entailed.
