In ancient China, in order to maintain the stability of the frontier, imperial clan women were often sacrificed to get married, and Princess You Jie was one of them. Liu, the daughter of a guilty minister, was crowned a princess and married Wusu. Wusu is located in today's Kazakhstan. Emperor Wu of the Han Dynasty accompanied Liu to Wusu for four years. As a princess of the Han Dynasty, Liu shouldered the heavy responsibility of educating barbarians and making them submit to the Han Dynasty.
Therefore, as Liu's right-hand man, he taught himself the languages of the countries in the western regions and was proficient in their languages. Unlike other women, Feng Heng is good at riding and healthy. So Liu sent her to the Western Regions to accompany the Princess Han Festival. Han Festival, granted by the Emperor of Heaven, represents the Han Dynasty, and Feng Heng's mission with Han Festival means that she is an envoy sent by the imperial court, so she is the first female diplomat in China.
Later, Wu Sun was in civil strife, and Wu Tu defected to the Han Dynasty. All the western regions sent Feng Gui to persuade Wu Tu to surrender. Although Feng Heng was a woman, she dared to enter the enemy's camp alone, and she was reasonable to Wu Tu, and successfully persuaded Wu Tu, which made great contributions to the Han Dynasty. This time, Feng Heng's name spread all over the government and shocked Xuan Di, the Emperor of the Han Dynasty. Emperor Xuan Di summoned Feng Heng back to Beijing and sent officials to meet him in the suburbs. Feng Heng proposed to Emperor Gaozu Xuan Di that he should be named Wu Jiutu to dispel his doubts. Emperor Xuan Di agreed, and then ordered Feng Heng to be Wu Sunguo's ambassador again. This time, Feng Heng's status as a diplomat was officially confirmed.
This mission was also very successful. Wu Guo Sun surrendered to the Han Dynasty, which unified the western regions. After three years of nectar, Liu He finally returned to Chang 'an. The following year, Liu died of illness, and the specifications of the funeral were in accordance with princess standards. Serina Liu became a princess of the Han Dynasty. The court also treated Feng Heng very favorably.
However, Wusun was in turmoil again, and Feng Heng immediately wrote a letter inviting himself to Wusun again. At this time, it was the Han and Yuan emperors' period, and Feng Gui had been to seventy years of age. However, seeing her resolute attitude, Emperor Hanyuan agreed to her request and took Feng Gui as China's ambassador to Wusunguo for the third time (only once to persuade Wu to surrender). This was Feng Heng's last mission, and he successfully appeased Wusun. However, there is no record of Feng Jingyi since then, and she should have died shortly after returning to Beijing.
Feng Gui made three missions in his life, and together with Liu brought peace to the Han Dynasty for more than half a century. She was brave and far-sighted, and later generations praised her as "female Sean".
