The objective of the article is not to decide who is "really" Miao, or to define a static, essential, primordial set of criteria for being a true Miao, but to identify what "Miao" has been meant in the Christian community in Shimenkan of Guizhou. Historically the Flowery Miao have constructed their identities by embracing Christianity in the early twentieth century and have had to reconstruct it after 1949. Dealing with the Western missionaries, the Chinese Republican government, and the local landlords, the Miao people in Shimenkan have attempted to reconcile both ethnic identity and Christian identity by developing education and the written language, which in turn signify them literately and culturally. Furthermore, the case of Shimenkan reveals the complicated process of intergrating ethnic minorities into the "Chinese" family and the construction of a new nation-state during the Republican era.
