When Liu Bei seized Yi Province from Lady Wu's brother-in-law Liu Zhang in 214, he had been effectively divorced from his wife Lady Sun, the younger sister of Sun Quan. Many of Liu Bei's subordinates encouraged him to take Lady Wu as his wife. However, he was hesitant due to the fact that Liu Mao and him were of the same clan. In order to convince Liu Bei, Fa Zheng reminded Liu that Duke Wen of Jin was betrothed to Huai Ying, even though he was the brother of her previous husband, Duke Huai of Jin. Therefore, Liu Bei agreed and he married Lady Wu.(先主既定益州，而孫夫人還吳，群下勸先主聘后，先主疑與瑁同族，法正進曰：「論其親疏，何與晉文之於子圉乎？」於是納后為夫人。) Sanguozhi vol. 34.
