2. No gold is barefoot, and no man is perfect.

3. People have joys and sorrows, separations and reunions, and the moon waxes and wanes. This is a difficult thing in ancient times.

4. Perfection is the standard of God, and the desire to achieve perfection is the standard of mankind. ——Goethe

5. Life is no longer a happy feast or festival-like jubilation, but an experience of work, struggle, poverty and suffering. ——Belinsky

6. No one is a sage, and no one can make mistakes.
