Nine in the fifth place means

If you are sincere and loyally attached,

You are rich in your neighbor.

Loyalty leads to firm ties because it means that each partner complements the other. In the weaker person loyalty consists in devotion, in the stronger it consists in trustworthiness. This relation of mutual reinforcement leads to a true wealth that is all the more apparent because it is not selfishly hoarded but is shared with friends. Pleasure shared is pleasure doubled.
