What is the most important value of Confucianism?

I know there are like 6 important values in Confucianism:

Li, Hsiao, Yi, Xin, Jen, and Chung.
I thought Jen was like the most important and well-known of the six, but I wasn't sure.

Is it the most important? If not, which one is it??

Thanks =]
And please put in details.
Links are appreciated too.

"The wise admit they know nothing"

-Confucius

Owwwwww my butt hurts

Confusis says

Man who runs in front of car gets tried
Man who runs behind car gets ex hasted

Confucius say, "Man entering turnstile sideways going to Bangkok."

you forgot Wang Chung, it is the essential value for your studies

You mean the concepts of Jen and Ren? Which are Benevolence and Justice. Those are two that are important. Confucius supported his "thesis" by promoting the 6 virtues of mathematics, music archery and i forgot what else). But he believed that a way to achieve the Dao, or perfect equanimity is by being wise, morally stable.
