These include the Hmu, Kho (Qho) Xiong, and A Hmao.
The White Miao (Bai Miao) and Green Miao (Qing Miao) are Hmong groups.
During this time, references to Unfamiliar (生 Sheng) and Familiar (熟 Shu) Miao appear, referring to level of assimilation and political cooperation of the two groups.
Not until the Qing dynasty (1644–1911) do more finely grained distinctions appear in writing.
In the version that passed the assembly, "Hmong" was replaced by "Southeast Asians", a more broadly inclusive term. Paoze Thao and some others feel strongly that "Hmong" can refer to only Hmong Der people and does not include "Mong" Leng people. They are also one of the sub-groups of the Miao ethnicity (苗族) in China.Thousands of economic and political refugees have resettled in Western countries in two separate waves.Even then, discerning which ethnic groups are included in various classifications can be problematic.This inconsistent usage of "Miao" makes it difficult to say for sure if Hmong and Mong people are always included in these historical writings.Hmong groups are often named after the dominant colors or patterns of their traditional clothing, style of head-dress, or the provinces from which they come.The Hmong groups in Vietnam and Laos, from the 18th century to the present day, are known as Black Hmong (Hmoob Dub), Striped Hmong (Hmoob Txaij), White Hmong (Hmoob Dawb), Leng Hmong (Hmoob Leeg) and Green Hmong (Hmoob Ntsuab).According to the 2000 censuses, the number of 'Miao' in China was estimated to be about 9.6 million.The Miao nationality includes Hmong people as well as other culturally and linguistically related ethnic groups who do not call themselves Hmong.They noted that despite nearly equal numbers of Hmong Der and Mong Leng in the United States, resources are disproportionately directed toward the Hmong Der community.This includes not only scholarly research, but also the translation of materials, potentially including curriculum proposed by the bill.
