Stanford PHD student Chen Shu Juo, regarding the ancestry of Southern Chinese [see this]. The author is a Taiwanese. The thesis is based on research of Y chromosome which indicates patrilineality as well as mtDNA, which is inherited only through mother.
The author deduces that Fujian Han receives 100% paternal genetic contribution from Northern Chinese and 34% maternal Northern Chinese contribution. Meanwhile Guangdong Han is 68% paternal and 15% maternal from Northern Chinese. Hence, the local woman maternal genetic contribution to Fujian and Guangdong people is 66% and 85% respectively.
There is this WholeX guy here who claim my Han ancester rape the indigenous women. So Lux felt ashame as "Chinese" and want to gain back my Malay identity.
If Fujian people are using Latin to form their own words, we will not be "Chinese".
That is why for the sake of China, as I am patriotic, I would like to see unification of writing system.
