1. Travel thousands of miles and read thousands of books.

2. There are roads in the mountain of books and diligence is the path, and there is no limit to the sea of ??learning and the boat is hard work.

3. I have read tens of thousands of books, and my writing is like a spirit.

4. Any valuable knowledge I have learned is from self-study. ——Darwin

5. If a young man does not work hard, the old man will be sad.
