初,郑武公娶于申,曰武姜,生庄公及共叔段。庄公寤生,惊姜氏,故曰寤生,遂恶之。
Duke Wu of Zheng had married a daughter of the House of Shen, called Wu Jiang, who bore duke Zhuang and his brother Duan of Gong. Duke Zhuang was born as she was waking from sleep ( the meaning of the text here is uncertain ), which frightened the lady so that she named him Wusheng (= born in waking ), and hate him.
