The strength of a wall is neither greater nor less than the courage of the men who defend it.

Not even a mighty warrior can break a frail arrow when it is multiplied and supported by its fellows. As long as you brothers support one another and render assistance to one another, your enemies can never gain the victory over you. But if you fall away from each other your enemy can brake you like frail arrows, one at a time.

All who surrender will be spared; whoever does not surrender but opposes with struggle and dissension, shall be annihilated.

Even when a friend does something you do not like, he continues to be your friend.

Heaven grew weary of the excessive pride and luxury of China... I am from the Barbaric North. I wear the same clothing and eat the same food as the cowherds and horse-herders. We make the same sacrifices and we share.. our riches. I look upon the nation as a new-born child and I care for my soldiers as though they were my brothers.

People conquered on different sides of the lake should be ruled on different sides of the lake.

The strength of walls depends on the courage of those who guard them.
