Bei
The term bèi refers to a particular style of moiety that is found among the Yan ethnicity.
Yanwen Factions
In most of modern Yanwen the moieties have evolved into political factions, each controlling part of the empire and competing land and resources amongst themselves, under the watchful eye of the Emperor.
Jianzhu Trade Societies
Zhi
The Society of Zhì (騭) is well-known for its trade with Kamura. It is a descendant of the Rose moiety, and indeed does much trade with the Rose faction in Yanwen.
Hui Bloodlines
Although the moieties appear to have remained in place for some time, eventually the families dominated by one particular "colour" took on that colour as their own. There are now thirty-two family lineages in Hui, each one specializing in a different economic activity.
Tianji Moieties
On the islands of Tianji, the moieties have remained effectively as they were some four thousand years ago: merely a way of keeping track of the generations, and of creating bonds between distant families and nations. There are also certain festivals celebrated by specific moieties.
