《史记·七十列传·张仪列传》
假如魏国向南与楚国友善而不和齐国友善，那么齐国就会攻打你的东面；向东与齐国友善而不和赵国友善，那么赵国就会攻打你的北面；与韩国不合，那么韩国攻打你的西面；不亲附楚国，那么楚国就会攻打你的南面；这就叫做四分五裂的地理形势啊。
梁南与楚而不与齐，则齐攻其东；东与齐而不与赵，则赵攻其北；不合於韩，则韩攻其西；不亲於楚，则楚攻其南：此所谓四分五裂之道也。
If the State of Wei remains friendly with the State of Chu in the south and is hostile to the State of Qi, then the State of Qi will attack the State of Wei from the east; if the State of Wei remains friendly with the State of Qi in the east and is hostile to the State of Zhao, then the State of Zhao will attack the State of Wei from the north; if the State of Wei is hostile to the State of Han, then the State of Han will attack the State of Wei from the west; if the State of Wei remains alienated from the State of Chu, then the State of Chu will attack the State of Wei from the south; this is the division and disintegration of the geographical situation.
