and Sun Quan. Because of her brother's strong influence, Lady Sun was arrogant and she allowed her close aides to behave lawlessly. Even Liu Bei was afraid of her. When Sun Quan heard that Liu Bei had left for Yi Province, he sent a vessel to Jing Province to fetch his sister home. Lady Sun attempted to bring along Liu Bei's son Liu Shan with her, but Zhang Fei and Zhao Yun led their men to stop her and managed to retrieve Liu Shan. Conquest of Yi Province Around 212, relations between Liu Bei and Liu Zhang deteriorated to the point of conflict, when Liu Bei started a campaign aimed at seizing Yi Province from Liu Zhang. Liu Bei ordered Zhuge Liang, Zhao Yun, Zhang Fei and others to lead reinforcements into Yi Province to help him, while Guan Yu remained behind to defend Jing Province.

In 214, Liu Zhang surrendered and yielded Yi Province to Liu Bei. Liu Bei rewarded Zhuge Liang, Fa Zheng, Zhang Fei and Guan Yu each with 500 jin of gold, 1,000 jin of silver, 50 million coins and 1,000 rolls of
