This paper critically examines the practice of multi-nation autonomy in longsheng, Guangxi. Interviewees show enormous frustration toward their own inability to do something about their life improvement. It is argued in this paper that the notion of multi-ethnic autonomy is an institutional constraint, locking local people into their own ethnic identities on the one hand, but keeping them from acting in the name of their people on the other. This is because each ethnic group is only a small component of the county and there is little incentive for any county officials to serve the multi-ethnic, which speaks nobody's nation indeed. Consequently, multi-ethnic autonomy is not different from Han autonomy, hence self-contradiction.
