Cheng Dachang of the Song Dynasty recorded that Hua Mulan lived during the Sui and the Tang Dynasties. Song Xiangfeng of the Qing Dynasty asserted that she was of Sui origins (AD 581-618) while Yao Ying, also of the Qing Dynasty, believed she was from the time of the Six Dynasties. No record of her achievements appears in official history books prior to the Song times. Stories circulated in China's Central Plains indicate that she must have lived before the Tang Dynasty.
Both history books and legends do at least agree on one thing - her accomplishments. It is said that Hua Mulan's father received an order to serve in the army. He had fought before but, by this time, was old and infirm. Hua Mulan knew it was out of the question for her father to go and her only brother was much too young. She decided to disguise herself as a man and take her father's place.
The troops fought in many bloody campaigns for several years before they obtained permission to return home. Hua Mulan was summoned to the court by the emperor, who wished to appoint her to high office as a reward for her outstanding service. Hua Mulan declined his offer and accepted a fine horse instead.
Only later, when her former comrades in arms went to visit her, did they learn that she was a woman.
The story of Hua Mulan is well known and has provided much inspiration for poetry, essays, operas and paintings.
