This work is an annotated edition of a ritual manuscript, written in the traditional Zhuang character script. The Hanvueng epic is a narrative in verse about murderous enmity between two royal step-brothers, recited when there is fraternal feuding, death by violence, outbreaks of smallpox, or other such disasters. The theme of enmity is an important one that resonates deeply in the Tai societies on the periphery of the Chinese empire. The narrative touches on many other aspects of life in the valley-kingdoms in the highlands of marriage and inheritance, match-making, slavery and social stratification, agriculture, hunting, fishing, raiding, livestock raising dye-making, wild animals and plants, and the use of ritual to put things to rights.
