The cultural landscape is unsurprisingly very diverse given the sheer size of the country. China has 56 officially recognized ethnic groups; the largest by far is the Han which comprise over 90% of the population. The other 55 groups enjoy affirmative action for university admission, and exemption from the one-child policy. The Han, however, are far from homogeneous and speak a wide variety of mutually unintelligible local "dialects"; which most linguists actually classify as different languages using more or less the same set of Chinese characters. Many of the minority ethnic groups have their own languages as well. Contrary to popular belief, there is no single unified Han Chinese culture, and while they share certain common elements such as Confucian and Taoist beliefs as a basis, the regional variations in culture among the Han ethnic group is actually very diverse. Many customs and deities are specific to individual regions and even villages. Celebrations for the lunar new year and other national festivals vary drastically from region to region. Specific customs related to the celebration of important occasions such as weddings, funerals and births also vary widely. In general contemporary urban Chinese society is rather secular and traditional culture is more of an underlying current in every day life. Among ethnic minorities, the Zhuang, Manchu, Hui and Miao are the largest in size. Other notable ethnic minorities include: Koreans, Tibetans, Mongols, Uighurs, Kirghiz and even Russians. In fact, China is home to the largest Korean population outside Korea and is also home to more ethnic Mongols than the Republic of Mongolia itself. Many minorities have been assimilated to various degrees with the loss of language and customs or a fusing with Han traditions. The exception to the rule is the current situation of the Tibetans and Uighurs in China who remain fiercely defensive of their cultures.3
