Nine in the fourth place means

The legs of the ting are broken.

The prince's meal is spilled

And his person is soiled.

Misfortune.

A man has a difficult and responsible task to which he is not adequate. Moreover, he does not devote himself to it with all his strength but goes about with inferior people; therefore the execution of the work fails. In this way he also incurs personal opprobrium.

Confucius says about this line:

“Weak character coupled with honored place, meager knowledge with large plans, limited powers with heavy responsibility, will seldom escape disaster.”
