The Mufu yanxian lu 幕府燕閒錄 "Records from the Banquets in the Prefects's Office", also written 幙府燕閒錄, is a biji 筆記 "brush notes" style book written by the Song period 宋 (960-1279) scholar Bi Zhongxun 畢仲詢, courtesy name Bi Jingru 畢景儒, who was prefectural judge (tuiguan 推官) in Lanzhou 嵐州 (modern Lanxian 嵐縣, Shanxi) during the Yuanfeng reign 元豐 (1078-1085). The book includes a lot of stories about famous persons like Fan Zhongyan 范仲淹 who mispelt a name of an official in a tomb inscriptions, or Ouyang Xiu 歐陽修, who defended a dog that had been trampled to death by an officials's horse, and many other less known persons like Wang Mou 王某 who criticized the custom to purchase an internship at the Directorate of Education (guozijian 國子監) by a donation of grain and called such a person a "grain professor" (gubo 穀博) instead of a "Directorate's professor” (guobo 國博). The stories cover a vast range of different themes and can be used as supplementary information to the biographies of the relevant persons. The word mufu in the title actually means the field tent of a general, especially if the latter has great authoritative rights and a certain grade of autonomy, but is later also used for the office of a local governor.
The original text was 10 juan "scrolls" long and was divided into 20 chapters. Fragments are preserved in the collectanea Shuofu 說郛 and Songren baijia xiaoshuo 宋人百家小說.
