1. Confucius: Keep learning and stop with the coffin closed.

2. Zhuangzi: My life has a limit, but my knowledge has no limit.

3. Xunzi: Learning is impossible.

4. Guanzi: There is no better plan for a year than a tree valley. A ten-year plan is better than growing trees; a lifelong plan is better than cultivating people.

5. Few but eager to learn, like the rising sun. Strong and eager to learn, like the light in the sun. Old and eager to learn, as bright as a candle.
