Chapter 28, Part 1C - Chuang Tzu

When the Great King Tan-fu was living in Pin, the Ti tribes attacked his territory. He offered them skins and silks, but they refused them; he offered them dogs and horses, but they refused them; he offered them pearls and jades, but they refused them. What the men of the Ti tribes were after was his land.

The Great King Tan-fu said, "To live among the older brothers and send the younger brothers to their death; to live among the fathers and send the sons to their death - this I cannot bear! My people, be diligent and remain where you are. What difference does it make whether you are subjects of mine or of the men of Ti?

"I have heard it said, one must not injure that which he is nourishing for the sake of that by which he nourishes it." Then, using his riding whip as a cane, he departed, but his people, leading one another, followed after him, and in time founded a new state at the foot of Mount Ch'i.
