This is a traditional story about the origin of the division into Bey subclans. Bey Ki’ik and Bey Ke’et have a falling out over changing marriage plans as a result of the grandmother’s advice. As a result, a taboo exists such that descendants of Bey Ki’ik and those of Bey Ke’et are not allowed to marry each other. Another result is that members of the Bey Ronghang clan are not allowed to grind rice for rice beer, because in mythological times, the Bey Ronghang women kept grinding rice for rice beer without doing anything else--even forgetting to breast-feed their children, who then died from starvation.
