(1) The Moral Law;
(2) Heaven;
(3) Earth;
(4) The Commander;
(5) Method and discipline.

The Moral Law causes the people to be in complete accord with their ruler, so that they will follow him regardless of their lives, undismayed by any danger.

The Commander stands for the virtues of wisdom, sincerely, benevolence, courage and strictness...”
