The lag in education~~~

That day I came across a piece about the lagging nature of education. It talked about how when we sat in the classroom listening to the teacher, we might not understand some knowledge, and some principles might not resonate with us. It wasn't until a certain day in adulthood that, through personal experience, we suddenly grasped some of the principles the teacher spoke of back then. Only then can we say that education has completed its final loop.
