Hakka are Han and only Han. So what if some She were assimilated that doesn't take away the fact Hakka is Han. Besides aren't the She a Yao-Mien related people?
It also doesn't take away the fact Hakka are mixed, only the mtDNA study shows Hakka are heavily mixed with southern aboriginals. Hakka have 31% Northern mtDNA but 58% Southern mtDNA. 62% northern Y-dna and 38% southern Y-dna. Cantonese 20-23% northern mtDNA but 70% southern mtDNA, but with 76% Northern Y-dna and 24% Southern Y-dna.

Chaoshan and Cantonese, Hakka difference in the genetic background of maternalhttp://eng.hi138.com/?i278537_Chaoshan_and...und_of_maternal[Abstract] the purpose of the Guangdong Department of the Han people or three large Chaoshan, Cantonese and Hakka are the descendants of landlocked Central China the Han immigrants, this study reflect the maternally inherited mitochondrial DNA (mtDNA) evidence of three major differences between the people of the genetic backgrounds . Chaoshan blood samples were collected 89 and 48 landlocked Central Plains high incidence of esophageal cancer among blood Taihang Mountain to build each individual's mtDNA haplogroups; Cantonese and Hakka haplogroup data from the literature. these 3 Department of a large crowd of people haplogroups and the distribution of population and the south of Taihang Mountain comparative analysis of Aboriginal people. Results Taihang Mountain Han people mainly from the north constitute the major haplogroups, Cantonese and Hakka, Aborigines South Main Zeyi haplogroup mainly Chaoshan showed major haplogroups in northern Han slightly above the main indigenous southern haplogroups. haplogroups based on the frequency of the principal component analysis, together Taihang Mountain and Chaoshan, Hakka and Cantonese people are aboriginal groups and the South together. Conclusion 3 large public system, only the Han nationality Chaoshan blood is more pure, and the closest Taihang Mountain population, which may also be the high-risk groups for the South coast of esophageal cancer One of the reasons; Cantonese Hakka and aboriginal people are in the South have more matrilineal descent blend.
