Yannian Li
China was a court musician in the Han Dynasty. Zhongshan (now Dingxian County, Hebei Province) was born to advocate family. Good at composing, singing and dancing. Emperor Wu of the Han Dynasty (Kloc-0/40 ~ 87 BC) entered the palace as an official (eunuch) because his sister was loved by Emperor Wu and made him a nobleman. Because of his outstanding musical talent, when Emperor Wu was in Yuefu, he was appointed as the captain of Yuefu. In the heyday of the Li family, his sister Lifu was the king of Changyi; His brother Li Guangli, a second general, was appointed as a military uniform. Li Fu died, and Li Yannian was imprisoned for his brother Li Ji's adultery with the harem. In 9O BC, Li Guangli surrendered to the Huns, and the whole family was exterminated. Li Yannian is a talented court musician. According to historical records, he was "moved by every new sound". About six years in Ding Yuan (1 1l BC), he wrote 19 "Ci of Sacrifice to the Suburb", written by Sima Xiangru, a famous scholar at that time. He can not only understand the requirements of Emperor Wu of the Han Dynasty for music, but also deeply understand these difficult "elegant articles". Li Yannian also composed 28 new songs according to Mukedule, which Zhang Qian brought back from the Western Regions, as military music for the ceremony. These pieces of music have been circulating for a long time, and 1O pieces of music, such as Huanggu, Longtou, Going through the Customs and Entering the Customs, can still be played in the Jin Dynasty hundreds of years later. This creative practice of adapting the tones of western regions into new songs not only embodies the high level of composition and erasure at that time, but also promotes the exchange of national music culture. Historical Records and Hanshu all listed him as a historical figure.
