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

People stumble and horses stumble.

A wise man will make a mistake after thinking a lot.

An inch is longer and a ruler is shorter.

People are not sages, and no one can do it without reason.

A ruler is shorter and an inch is longer.

Gold has no color, and white jade has slight flaws.

Sweet melon and bitter stem, nothing in the world is perfect.

No gold is pure and no one is perfect.

No one is born knowing, how can one be free from confusion.

Since there are black spots on the sun, it is even more impossible for "things in this world" to be without flaws.

Because they have flaws, people are willing to tolerate their successes. It also often causes potential rivals to ignore their competition and challenges.

Never try to cover up the flaws in your knowledge, even with the boldest speculations and assumptions.

Nothing is ever finished and no one is perfect.

A slightest mistake is a thousand miles away.
