China: 'Court Ladies Wearing Flowered Headdresses'. Detail of handscroll painting by Zhou Fang (c. 730-800), late 8th century. Consort Yang Yuhuan (719-756), often known as Yang Guifei (Guifei being the highest rank for imperial consorts), known briefly by the Taoist nun name Taizhen, is famous as one of the Four Beauties of ancient China. She was the beloved consort of Emperor Xuanzong of Tang during his later years. During the Anshi Rebellion, as Emperor Xuanzong was fleeing from the capital Chang'an, she was murdered because his guards blamed her cousin Yang Guozhong for the rebellion.
