third century) was a Chinese historian and travel writer of the state of Cao Wei during the Three Kingdoms period.
[1] He is best known for writing the Weilüe and Dianlüe, privately composed histories which according to the Book of Sui, comprise 33 and 89 fascicles respectively.
[1] Neither of these works are extant, however a volume of the Weilüe was quoted as an extensive footnote to the Records of the Three Kingdoms in the (30th) section on the Wuhuan, Xianbei and Dongyi by Pei Songzhi in 429 CE.
[3] In spite of the inclusion of earlier (and sometimes fanciful) information, the Weilüe contains much new, unique and generally trustworthy material.
While Yu Huan's own sources are difficult to assess,[5]: 328 much of his information appears to date from the Eastern Han dynasty, before China was largely cut off from the West by civil wars and unrest along its borders during the late 2nd century CE.
