《管子·霸言》
强国的正确作法是容纳小国，其失误在于自恃其强；小国的正确作法是折节事强，其失误在摆脱强国。
强国得之也以收小，其失之也以恃强。小国得之也以制节，其失之也以离强。
The right way for a strong state is to take in the weak; its mistake lies in relying on its strength; the right way for a weak state is to submit to the strong; its mistake lies in breaking away from the strong.
