The expansion and development of Yuefu in the Western Han Dynasty was in the period of Emperor Wu of Han Dynasty. The Book of Rites and Music in Han Dynasty said: "By the time Emperor Wu made a decision, Yuefu was established, reading poems at night, entrusted by Zhao, Dai, Qin and Chu. With Li Yannian as the captain of the Concordia, he quoted dozens of artificial poems such as Sima Xiangru. This paper briefly discusses the Law, and composes an eight-tone ensemble with chapter 19. On the first day of the first month, people worship the hills with sweet springs, which makes 70 boys and girls faint. " During the period of Emperor Wu of Han Dynasty, the function of Yuefu was further strengthened. It not only organizes literati to create songs and poems for the use of the imperial court, but also widely collects ballads from all over the country. Many folk songs are sung in Yuefu and handed down. The Yuefu poems created by literati are no longer limited to Song Like's banquet in Anshifang, but also sung during the festival, and the status of Yuefu poems is obviously improved. According to "Han Shu Guan Bai Gong Qing Biao", when Emperor Wu of the Han Dynasty was in power, the Yuefu Order consisted of three officials. According to the History of Rites and Music in Han Dynasty, by the end of Emperor Wu of Han Dynasty, Yuefu had more than 800 employees and became a large-scale music institution. More than 100 years from Emperor Wu of the Han Dynasty to Emperor Cheng was the heyday of Yuefu. Emperor Ai ascended the throne, ordered the dismissal of Yuefu officials, greatly reduced Yuefu personnel, and placed the rest under the jurisdiction of the order. Since then, there has been no Yuefu organizational system in the Han Dynasty.
The organ in charge of music in the Eastern Han Dynasty also belonged to two systems. One is Taiyue Music Department, and the chief executive is Taiyue Music Order, which is equivalent to Taiyue Music Order in the Western Han Dynasty and belongs to Taichangqing. One is the propaganda department of Huangmen, in charge of Cheng Hualing, belonging to Shaofu. The name of Huang Men's advocacy has existed since the Western Han Dynasty, and it has a very close relationship with Yuefu. In the Eastern Han Dynasty, the Huangmen Propaganda Department, which was in charge of Cheng Hualing, provided songs for the ministers who enjoyed the banquet, which actually played the role of Yuefu in the Western Han Dynasty. Yuefu poems in the Eastern Han Dynasty were mainly sung by Huangmen Propaganda Department, so they were preserved.
During the Wei and Jin Dynasties, some old Yuefu songs were still in use, and a considerable number of Yuefu poems in the two Han dynasties were circulated inside and outside the court. Some collections in the Six Dynasties specially included ancient Yuefu poems, mainly Yuefu poems in the two Han Dynasties. Shen Yue, the wise man, compiled The Book of Song Dynasty, and his Le Zhi included many poems of the Han Dynasty. Yuefu Poetry, compiled by Guo Maoqian, a Song Dynasty, includes Yuefu Poems in Han and Tang Dynasties, which are divided into 12 categories: Jiaomiao Ci, Ci, Advocating Ci, Crosswind Ci, Harmony Ci, Dance Music Ci, Qin Ci, Miscellaneous Ci, Modern Style Ci, Miscellaneous Ci and New Yuefu Ci. Yuefu poems in the two Han dynasties are mainly preserved in suburban temple songs, preaching songs, harmony songs and miscellaneous songs, with the largest number of harmony songs.
The authors of the existing Yuefu poems in the two Han dynasties cover all levels from emperors to civilians, some of them are written in temples and some are collected from the people. Sima Xiangru and other famous literati also participated in the creation of Yuefu poems. The Records of Han Yi Wen recorded 28 songs and poems of the Western Han Dynasty, 3 14, all of which were Yuefu poems. At present, the works of Yuefu poetry in the Western Han Dynasty can be determined as follows: Da Feng Ge, An Shi Fang Ge 17, Jiao Si Ge 19, cymbals Song 18, and a few other folk songs. Other Yuefu poems were written in the Eastern Han Dynasty.
