Teaching and Learning Promote Each Other.
Teachers and students improve each other. The ancient Chinese realized that teaching is not just a matter of teachers influencing students, but a two-way process of mutual interaction. In this process, teachers and students continuously make their own progress and improvements. It embodies the view that both teachers and students can benefit from their interactions, which is quite similar to the views of modern education.
Learning makes you find out your shortcomings, and teaching makes you find out that you still have room for improvement. When knowing your shortcomings, you can think about them and make improvements; knowing you still have room for improvement, you can work hard to close the gap. That is why we believe that teaching and learning promote each other. (The Book of Rites)
