Ban Jieyu (48 BC-2 AD), whose name is unknown, was the concubine of Liu Ao, the emperor of the Han Dynasty, a female writer in the Western Han Dynasty, and a famous talented woman in ancient times. She is one of the female writers who are good at Ci and Fu in the history of China literature. Good poem, good virtue. First a few ambassadors, but a tribute. There is a biography of her in the biography of Han consorts. She is also the grandparents of Ban Gu, Ban Chao and Ban Zhao. She has many works, but most of them have been lost. There are only three existing works, namely "Self-injury Fu", "Knife" and a five-character poem "Song of Sorrow" (also known as "Song of the Lost"). 1 (Ban Jieyu portrait source 1)
