The idea of single language has major overtones in politics and self-identity, and explains the amount of emotion over this issue. The idea of Chinese as a language family may suggest that China consists of several different nations, challenge the notion of a single Han Chinese nationality, and legitimize secessionist movements. This is why some Chinese are uncomfortable with it, while supporters of Taiwan independence tend to be strong promoters of Min- and Hakka-language education. Furthermore, for some, suggesting that Chinese is more correctly described as multiple languages implies that the notion of a single Chinese language and a single Chinese state or nationality is artificial.
However, the links between ethnicity, politics, and language can be complex. Many Wu, Min, Hakka, and Cantonese speakers consider their own varieties as separate spoken languages, but the Han Chinese nationality as one entity. They do not regard these two positions as contradictory, but consider the Han Chinese an entity of great internal diversity. Moreover, the government of the People's Republic of China officially states that China is a multinational state, and that the term "Chinese" refers to a
broader concept Zhonghua Minzu that incorporates groups that do not natively speak Chinese, such as Tibetans, Uyghurs, and Mongols. (Groups that do speak Chinese are properly called Han Chinese, and are regarded as one component of a multi-ethnic whole.) This is seen as an ethnic and cultural concept, not a political one. Similarly, on Taiwan, some supporters of Chinese reunification promote the local language, while some supporters of Taiwan independence have little interest in the topic. And the Taiwanese identity incorporates Taiwanese aborigines, who are not considered Han Chinese because they speak Austronesian languages, predate Han Chinese settlement, and are culturally and genetically linked to other Austronesian-speaking peoples such as the Malays and Polynesians.
