Yugong zhinan 禹貢指南 "Compass to the Tribute of Yu" is a commentary on the chapter Yugong 禹貢 of the Confucian Classic Shangshu 尚書 written by the Song period 宋 (960-1279) scholar Mao Huang 毛晃 (jinshi degree 1151, courtesy name Mingquan 明權), who was a famous poet and lexicographer.
Except his Yugong commentary he wrote a revision of the dictionary Libu yunlüe 禮部韻略. The 4-juan long Yugong zhinan comments on a large amount of older texts, like the glossary Erya 爾雅, the Classic Zhouli 周禮, the geographic treatise (28 Dili zhi 地理志) in the official dynastic history Hanshu 漢書, the river geography Shuijingzhu 水經注 or the treatise Jiuyuzhi 九域志, and tries to reconstruct the geography of China during the late Warring States period 戰國 (5th cent.-221 BCE), when the Yugong was written. Unfortunately Mao Huang lived in the Southern Song empire 南宋 (1127-1279) and was not able to personally inspect places in northern China because this was part of the Jin empire 金 (1115-1234). His book nevertheless inspired quite a number of later commentators on the Yugong chapter.

The Yugong zhinan was lost for a long time, but could be reconstructed with the help of quotations in the Ming period 明 (1368-1644) encyclopaedia Yongle dadian 永樂大典. It can be found in the collectanea Congshu jicheng chubian 叢書集成初編, Lizhizhai congshu 勵志齋叢書, Qingfentang congshu 清芬堂叢書, Rongyuan congshu 榕園叢書, Siku quanshu 四庫全書 and Wuyingdian juzhenban shu 武英殿聚珍版書.
