Jia Yi basically lived in a peaceful and stable environment during his childhood and adolescence, and his life was basically based on reading and writing. At the age of 18, he was famous in the county for his ability to recite poems and write articles. At that time, Wu Tingwei, the governor of Henan Province, appreciated his talents and learning and made him his disciple. In 180 BC, Emperor Liu Heng of Han Dynasty ascended the throne. Hearing that Wu Gong, the governor of Henan, was quite knowledgeable and had outstanding political achievements, he recruited Wu Gong as a court lieutenant. In the first year of Emperor Yuan of the Han Dynasty (179 BC), Jia Yi was recruited into the court and became a doctor on the recommendation of his teacher Wu Tingwei. Within a year, he was promoted to Taizhong doctor. From then on, the 22-year-old Jia Yi embarked on an official career and became a member of the political group of the Western Han Dynasty. Emperor Wen of the Han Dynasty valued Jia Yi very much. He promoted him to the rank of Taizhong doctor, and discussed with other ministers to promote him to the rank of public minister. However, he was opposed by the ministers. After that, Emperor Wen of the Han Dynasty began to deliberately alienate Jia Yi and sent him to be the Taifu of the King of Changsha. Jia Yi, who was politically frustrated, said goodbye to the capital and came to remote Changsha. He heard that Changsha's terrain was low and the humidity was high. He thought that if he went to Changsha, he would not live long. Moreover, because he was demoted, he was in a very bad mood. He often compared himself with Qu Yuan. In this case, he wrote "Ode to Qu Yuan" which has been passed down through the ages. In the seventh year of Emperor Wen of the Han Dynasty (173 BC), Emperor Wen missed Jia Yi who was far away in Changsha, so he summoned him into the palace. After listening to Jia Yi's grand remarks, Emperor Wen of the Han Dynasty said with emotion: "I haven't seen Jia Yi for a long time, and I think I have done something wrong, but I am not as good as I am now." Not long after, Emperor Wen of the Han Dynasty worshiped Jia Yi as the tutor of King Huai of Liang. During his tenure as Taifu of King Huai of Liang, Jia Yi was still very concerned about political affairs and dared to express his own opinions. He wrote famous articles such as "Public Security Policy" and "On Accumulation and Storage". In the eleventh year of Emperor Wen of the Han Dynasty (169 BC), Liu Yi, King Huai of Liang, came to the court and unfortunately fell from his horse and died. Jia Yi felt that he had not fulfilled his responsibilities as the tutor of King Huai of Liang, so he was very sad. A year later, due to excessive sadness, Jia Yi also died at the age of 33 in the twelfth year of Emperor Wen of the Han Dynasty (168 BC). Although Jia Yi's life was short, in this short life, he left a precious cultural heritage for the treasure house of Chinese culture. He is a representative writer of Sao style Fu, and his representative works are "Fu on Diao Qu Yuan" and "Ode on Song Bird". In the field of Western Han political prose, Jia Yi's prose can also be said to be of outstanding literary talent. Liu Xie's "Wen Xin Diao Long. Zuo Qi" said that the memorial is "both clear in theory and smooth in speech, which can be said to be a general understanding." His most praised political works are "On the Passage of the Qin Dynasty", "Public Security Policy" and "Policy of Public Security". "On Accumulation and Storage".
