Feng Liao (馮嫽) was China's first official female diplomat,[citation needed] who represented the Han dynasty to Wusun (烏孫), which was in the Western Regions.
It was a practice for the Imperial Court to foster alliances with the northern tribes via marriage, and two Han princesses had married Wusun kings.
Feng Liao was the maidservant of Princess Jieyou (解憂公主), who was married off to a Wusun king.
Feng herself later married an influential Wusun general, whose good standing with Prince Wujiutu (烏就屠) of the kingdom later proved beneficial to the Han dynasty.
In addition to those texts, a collection of Han bamboo and wooden slips found in Dunhuang described some of Feng Liao's life in Wusun.
