3. The essence of learning is not as good as knowing it; the essence of knowing is not as practical as practicing it.

4. It is said that Mr. ***’s words are better than ten years of reading. If he talks thoroughly, it will take more than ten years.

5. Studying is like trying to sail a boat on water, and you must not slow down for a moment.

6. Be honest and respectful in all things, and do not be arrogant or domineering to others or bring shame on yourself.

7. When studying a book, you will have doubts about the unknown at the beginning; secondly, you will gradually have doubts; and in the middle, you will have doubts all the time. After this, doubts will gradually be cleared up, until you have a thorough understanding and no doubts, and then learning begins.

8. If heaven does not give birth to Zhongni, eternity will be like a long night.
