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 "brush-notes"-style book (biji 筆記) written during the Song period 宋 (960-1279) by Bi Zhongxun 畢仲詢 (fl. 1082), courtesy name Jingru 景儒, who was prefectural judge (tuiguan 推官) in Lanzhou 嵐州 (modern Lanxian 嵐縣, Shanxi) during the Yuanfeng reign-period 元豐 (1078-1085). 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 book includes a lot of stories about famous persons like Fan Zhongyan 范仲淹 (989-1052) who misspelt a name of an official in a tomb inscriptions, or Ouyang Xiu 歐陽修 (1007-1072), who defended a dog that had been trampled to death by an officials's horse, and many other less known persons like a certain Mr Wang 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.
