The first poet specializing in writing ci in the Northern Song Dynasty.

Liu Yong was the first poet who devoted himself to the creation of Ci in the Northern Song Dynasty.

Liu Yong (about 984- about 1053), formerly known as Sanbian, whose word is Jingzhuang, was later renamed Liu Yong, whose word is also known as Liu Qi. He was born in Feixian County, Yizhou (now Feixian County, Shandong Province) and was a representative of graceful and restrained school.

Liu Yong was born in an official family. His predecessor was the Liu family in Hedong, a medieval gentry. He studied poetry when he was young and had the ambition to make a name for himself. In the fifth year of Xianping (1002), Liu Yong left his hometown and moved to Hangzhou and Suzhou, indulging in a life of drinking and singing. In the first year of Dazhong Xiangfu (1008), Liu Yong went to Beijing to take the imperial examination, and failed repeatedly, so he devoted himself to writing lyrics.

In the first year of Jing You (1034), in his twilight years, Liu Yong served as the promotion officer of Zhou Mu Yong ying, the magistrate of Yuhang County, the salt supervisor of Xiaofeng, and the judge of Sizhou. He was appointed as an official by Yuan Wailang, so he called Liu wasteland.

Liu Yong was the first poet who made a comprehensive innovation in Song Ci, and also created the most tunes in Song Ci. Liu Yong worked hard to create slow ci, transplanted his fu method into ci, and at the same time made full use of vulgar language, which had a far-reaching influence on the development of Song ci with its unique artistic personality such as appropriate image, incisive description and plain line drawing.

In the first year of Zhongxiang House (1008), Liu Yong entered Beijing Bianjing (now Kaifeng). In the Northern Song Dynasty, the capital was very prosperous. Liu Yonglingyun's ci-fu described the "beautiful weather" of the Imperial Capital as "the best song".
