If you study alone without friends, you will be lonely and ignorant.

If a jade is not polished, it will not become a tool. If a person does not learn, he will not know.

Although there are fine dishes , If you don’t eat, you don’t know its purpose; although there is a perfect way, if you don’t learn, you don’t know its goodness.

That’s why, after learning, you will know your shortcomings. After teaching, you will know your difficulties, and then you can become self-reliant.”

After learning, you will know your shortcomings; after teaching, you will know your difficulties. If you know your shortcomings, you will be able to reflect on yourself;

After you know your difficulties, you will be able to improve yourself.
