Original: Although there is delicious food, I don't know its purpose; Although there is supreme Tao, learning, I don't know its goodness. It is to learn and then know the deficiency, and to teach and then know the difficulty. If you don't know enough, then you can reverse; Advance despite difficulties, and then strive for self-improvement. So teaching and learning are also beneficial. "Duiming" said: "Learning half, this is nothing!"
Although there are delicious dishes, you don't know if they are sweet unless you eat them. Although there is the best truth, you don't know its benefits unless you study. Therefore, after learning, you will know your own shortcomings, and after teaching, you will know that you are confused. Know your own shortcomings so that you can reflect on yourself later; Know where you are confused, so that you can encourage yourself later.
Therefore, preaching, teaching and solving doubts complement each other. Teaching others can also increase your own knowledge. The book "Redemption" says: "Teaching is half of learning, which is probably the reason!"
Note: Avenue: refers to the political system respected by Confucianism in ancient times.
