If language is not correct, then what is said is not what is meant; if what is said is not what is meant, then what must be done remains undone; if this remains undone, morals and art will deteriorate; if justice goes astray, the people will stand about in helpless confusion.

There are 3 elements essential in the matters of the State, Food, Military equipment, and Confidence of the people in the ruler.
