Jia Yi (200 BC-65438 BC+068 BC), a native of Luoyang (now east of Luoyang, Henan), was a famous political commentator and writer in the early Western Han Dynasty, and was called Jia Sheng. Jia Yi is a rare talent. At the age of eighteen, he was considered a good writer in the county. Wendi was a doctor at that time, and later moved to be a doctor in Taizhong. He was pushed out by ministers Zhou Bo and Guan Ying and was promoted to be the teacher of King Changsha, so later generations also called Jia Changsha and Jia Taifu. Three years later, he was recalled to Chang 'an to be the teacher of Liang Huaiwang. Liang fell off his horse and died. Jia Yi was deeply sorry and died of depression at the age of 33. Sima Qian sympathized with both Qu Yuan and Jia Yi, and wrote a joint biography for them, so later generations often referred to Jia Yi and Qu Yuan as "Qu Jia".

Jia Yi's works are mainly prose and ci-fu, which are deeply influenced by Zhuangzi and Liezi [1].

. The main literary achievements of prose are political essays, commenting on current politics, simple style and vivid discussion. Lu Xun called it "Hong Wen of the Western Han Dynasty", and his masterpieces include On Qin, On Accumulation and Storage, and Chen Zheng's Poems. His Ci and Fu are both in Sao style, and tend to be scattered in form, which is the forerunner of the development of Han Fu, especially Qu Yuan Fu and Fei niao Fu.
