Six in the fifth place means:

Wise approach.
This is right for a great prince.
Good fortune.

A prince, or anyone in a leading position, must have the wisdom to attract to himself people of ability who are expert in directing affairs. His wisdom consists both in selecting the right people and in allowing those chosen to have a free hand without interference from him. For only through such self-restraint will he find the experts needed to satisfy all of his requirements.
