This is an interesting story, it is sad she has to suffer because of her parents immoral actions. Then again, I was told many times on this site that based on history and the current government in China someone who acts Han is Han and China is a multiethnic nation, no longer a Han dominated empire, so what is the issue? Isn't this girl just Shanghainese?
Thats not what the current goverment in China saids at all. You can't be a Han by just acting Han. Your ethnic group is determined by your birth and written on your passport. The only way you can choose is if you are of mixed ethnic descent. The PRC is a state that includes these 56 ethnic groups and exclusively these ethnic groups, which means that if you are not from one of the 56, meaning Africans and westerners, then you will have an extremely difficult time getting a Chinese citizen(I don't even think there is an official law in China that allows foreigners to become Chinese yet) Thats the difference between China's multi-ethnic nationstate and those that exist in the US.
