三年后，幽王衰败，桓公死了，他的儿子武公和平王向东迁移，终于安定号国、会国的土地，右边是雒，左边是沸，饮用溱水和洧水。
后三年，幽王败，桓公死，其子武公与平王东迁，卒定虢、会之地，右雒左泲，食溱、洧焉。
Three years later, King You fell. Duke Huan died. His son Duke Wu and King Ping moved east, and they finally settled in the lands of the states of Guo and Hui: to the right is the Luo, to the left is the Fei, and he drank from the Qin and Wei.
