In the ancient and modern word world, Liu Yong icon is definitely a famous lyricist who can rival the ancient word emperor Li Yu icon. One of his early scientific expeditions was frustrated: "Crane Soaring sky on the golden list" is an important work of his. Liu Yong was already very famous in the Northern Song Dynasty when he first conducted scientific expeditions, and his great name can be said to be well-known and thunderous, and the Northern Song Notes once said: "Where there is well water to drink, it is a song Liu Yong", "The musicians of the church have no new cavity, they must seek eternal words, and they will start in the world". Therefore, after the scientific expedition failed, he made this poem with a big grumbling and sighing speech, and later Song Renzong was very dissatisfied when he read this poem, and with a large stroke of the pen, Liu Yong "went to sing in a shallow and low voice, why should he float his name", and deposed him.
Since then, Liu Yong has claimed to be a person who fills in the words according to the will, and has wandered in the major wind and moon places all his life, and the Chinese word scene has also had a shining talented lyricist.

Liu Yong's thinking is contradictory, he called himself "Baiyi Qingxiang" in his words, but he could not completely put down his official meritorious name, and later changed his name and then examined, but his career was not smooth, and the official to Tuntian was a member of the foreign lang, so it was also called: "Liu Tuntian." Due to the bumpy career and the sloppy life, Liu Yong was tired of the officialdom and turned to filling in words with his life's energy.
