This paper describes four seas that are traversed bymemoed (female ritual specialists) during rituals among the Zhuang in Jingxi,Guanxi, China. It describes the different meanings of “crossing seas” to Zhuang individuals, Zhuang society, and Zhuang ritual specialists. At the same time, it discusses how “crossing seas” plays contributes to the continuity of the Zhuang people as a group, and represents important parts of their cosmology and historical background. The four seas are Haij Lungz Va, Haij Taem Gyang, Haij Yah Va, and Haij Zoi Slay. Formemoed, crossing seas demonstrates their ritual ability and is a means to strengthen their powers. For Zhuang society, the first three seas serve the role of guaranteeing safety through transitions and the continuity of the Zhuang people. The fourth sea is where the power of ritual specialists is strengthened and renewed. In analyzing the choice to use the borrowed Han Chinese term “hai” (sea) as a metaphor for a dangerous place or a place where one can gain strength and power, I argue one must consider the context of the area’s history before we can have a complete understanding of Zhuang ritual chanting.
