Yan Shu was the first prime minister of Fuzhou in the Northern Song Dynasty. Yan Shu and his seventh son Yan Daoji were called "Wild Goose" and "Xiao Yan" in the Northern Song Dynasty. At the age of fourteen, he took the entrance examination as a child prodigy, was awarded the pedigree of a kindred spirit, and was appointed as the secretary to preserve orthography. Later, he moved to Taichang Temple, Guanglu Temple Cheng, Yuan Wailang of Shangshu Province, Shiren of the Prince, Bachelor of Hanlin and Zuo Xiang. After Injong acceded to the throne, he moved to the right to discuss the doctor's degree. He joined the Ritual Department as an assistant minister, worshipped Emperor Taizong, studied politics, added history books to Zuo Cheng, and worshipped the bachelor of Jixiang Temple. Yan Shu occupied an important position, and was even promoted to a junior position, such as Fan Zhongyan, Han Qi and Ouyang Xiu. He writes poetry in the literary world and is particularly good at it. There are more than 0/30 congratulatory messages/KLOC-with subtle and graceful style, expressing poetry, wine and leisure. Influenced by Feng Yanqi in the Southern Tang Dynasty, he and Ouyang Xiu were also called "terns". Representative works include Huanxisha, Butterfly Lovers, Treading on the Stream, Breaking the Array, Magpie Knocking on Branches, etc. Among them, Huanxisha's sentence "I can't help falling flowers, but I seem to meet a swallow" is a famous sentence that has been passed down through the ages. His poetry creation is also excellent. The original 240-volume collection of poems has now disappeared, only the words and manuscripts edited by Hu in the Qing Dynasty. There is also a class book "Yao Ban", which is the remnant of the present.
