"Respectful and Lamentable Empress"), was an empress of the state of Shu Han in the Three Kingdoms period. She was a daughter of the Shu general Zhang Fei. She married Liu Shan in 221 and became the crown princess of Shu. In 223 when Liu Bei died, Liu Shan ascended the throne of Shu, and Zhang became the empress.
