From the Intrigues of the Warring States.

溫人之周，周不納。「客即？」對曰：「主人也。」問其巷而不知也，使因囚之。君使人問之曰：「子非周人，而自謂非客何也？」對曰：「臣少而誦《詩》，《詩》曰：『普天之下，莫非王土；率土之濱，莫非王臣。』今周君天下，則我天子之臣，而又為客哉？故曰主人。」君乃使吏出之。

A man from the state of Wen traveled to the state of Zhou, but the Zhou would not admit him. “Do you come as a foreign visitor?” He answered: “No, as a resident.” When asked for his address he could not provide any, so they imprisoned him. The ruler sent officials to question him. They said: “You’re not from Zhou, so why did you deny you were a foreigner?” He answered, “As a boy I learned to recite from the Book of Odes, where it is written: ‘Under the wide heaven / No land but is the king’s land; / To the edges of the earth, / No man but is the king’s subject.’ Today the Zhou rule over the world*, so of course I am a subject of the Son of Heaven, and you want to treat me like a foreigner? That’s why I said I was a resident.” The ruler told his officials to let him go free.

* This was of course very far from being the case at the time of the incident, but an residue of long-outdated Zhou royal entitlements.
