The same source I've mentioned in other threads. Go read Dru Gladney's book "Muslim Chinese".. it is probably the most comprehensive and most authoritative study on the Hui nationality.
this is not a question of how it works. It is a fact that since the government started applying benefits to minorities, people such as those with the surname "Ma" attempted to reclassify themselves as Hui. The population surge in the 70's and 80's testify to this reclassification as the numbers are beyond what the birth rate numbers existing population is able to produce
its not like"ok,huis gets more benefits,therefore i will become a hui now" it does not work like that,you think the government just let people chose whatever ethnic they want to be?
Some Hui's, not all Hui's. It is a fact that there were conversions done. It is a fact that there were conversions done in Yunnan, which probably explains why there are Bai speaking Hui.
its not a fabrication by the government. its a bloody fact that we huis have ancestors from arabs,persians and turkic muslims.
In the end you can grab a bunch of pictures of Hui's who look different to prove your point, but it's easy to grab a bunch of Hui's who do look Han to prove my point. The truth is in numbers and history. Ming Loyalist is right.. not every Hui is like those from Ningxia. And it is a FACT that both the Soviets and Chinese have constructed nationalities.
