I have been reading the chinese article on Zhonghua Minzu 中华民族 at http://zhidao.baidu.com/question/288438.html?si=2. It gives a somewhat historical perspective and a new 'nationalistic' point of view , given the fact that there are over 100 million overseas chinese outside China and take a look at the change of this definition over time.
As you may well know, this term surfaced around the corner during late Qing period, in response to the multi-ethnicities in Qing empire. The concept was later expanded to 5 ethnicities during early ROC period by Sun Yat Sen and then to 56 ethnicities in PRC. Today, the concept had include overseas chinese (about 100 million). This is a construction of a large supra ethnic group union transcending nationality and international boundaries (stemming from a nationalistic view), as PRC opened up to have contacts with outside world
The so-called "ZhongHua Minzu" ( short form - "Hua Ren 华人") is simply a large supra chinese ethnic groups union (multi-ethnic community) that transends nationality and international boundaries.
It includes:
1. Han-chinese (majority ethnic nationals/citizens living in China)
2. Ethnic Minorities (chinese citizen) living in China such as Manchu, Tibetan, Mongols, Uighur, Zhuang, Miao etc.
3. Overseas chinese (whose roots can be traced back to China, including ethnic minorities migrated overseas)
4. Ethnic Minorities in chinese history such as Xiongnu, Xianbei, Jie, Tujue, Khitan, Jurchen, Tanguts etc.
The chinese definition of "chinese" had discarded one based on blood origin and switched in favor to one based on culture and then balanced it with a nationalistic point of view. The definition of "chinese" based on blood was discarded simply because it was not able to complement the large multi-ethnic mix nature of people in China from historical perspective. It was also highly racist/discriminatory. The change to one based on chinese culture (including ethnic minorities culture) was more appealing to bind the ethnicities to China. More recently, with the presence of large population of overseas chinese who were trying to find ties with their roots or culture, China decided to expand the notion of this "Hua Ren" (Zhonghua Minzu) to include overseas chinese.
There are some controvesy esp. with Tibetan/Uighur/Taiwanese Independence group overseas.
What do you think of this Supra "Chinese Ethnic Groups Union"?
