China

When you know a thing, hold that you know it; when you do not, admit that you do not. That is knowing.

知之為知之，不知為不知，是知也。

What you do not want for yourself, do not do to others.

己所不欲，勿施於人。

To have friends come from far away: is that not a joy?

有朋自遠方來，不亦樂乎？

The country is broken, yet its mountains and rivers remain; spring comes to the city, and the grass and trees grow deep.

國破山河在，城春草木深。

A journey of a thousand li begins beneath your feet.

千里之行，始於足下。

Knowing others is wisdom; knowing yourself is clarity.

知人者智，自知者明。

Know the other side and know yourself, and in a hundred battles you will not be in danger.

知彼知己，百戰不殆。
