Yuhuanyi

The most common secret language used is the Yuhuanyi. Originating from the Queqiao Province, it is used primarily among the Queqiao women as a means of sending out secret messages, or to speak without being understood. While nowadays it is a sacred language used by women and seers within the Queqiao province, it was once a language of revolution and overcoming oppressive patriarchal forces. In the old days, this language was used as a means of getting around the power that men had in the household, and to act “nefariously”, or not in line with what the man of the household deemed was correct or appropriate; in those days, it was as simple as interacting with the outside world, learning from outsiders, etc.
The language first came to bear during a war between the tribes. With no intermediaries, no likeness for diplomacy, and a cultural focus on domination influenced by the environment where they lived, war was common and bloody. Revenge was seen as honorable and necessary to keep the powerful in check. Might made Right, so domination was how the strongest perpetuated society. Women, then, among other items, were prized commodities whose sole purpose was to bear babes for war; an echo of this in their present-day society can be seen in how young a child would be considered an adult--8 years. In order to speak, then, whether across enemy lines, in secret, or to outside forces that were taught the language, this language was thus used.
Trade is what spread the language outside those borders, and this language moved into almost all circles of society over the course of hundreds of years to become a language of revolutionary women; it signified, back then, who was an ally to women and who was not. As such, this language was later learned by men, but in less volume.
Nowadays, the language is used by women and the Leshen elders, keeping the tradition of the language being spoken by women only, for it is though that they can better handle sacred matters; the 8th birthdays of Quequao children who go to tame their Thunderbird in the Thunderbird Birthday, and other like events.
