How do Ibo pass down wisdom in the book Things Fall Apart?

Basic interaction is how most wisdom is passed down.

Okonkwo, in particular, tells his children war stories. People tell each other fables. In general, people interact with each other, whether through large ceremonies like weddings, funerals, trials, rituals, and competitions, or smaller every day things like the weekly market, farming, small-talk, etc. People often use parables in their speech to make moralistic points.
