History: Then And Now, China

Several ethnicities have also dramatically shaped Han culture, e.g. the Manchurian clothing called the qipao became the new "Chinese" fashion after the 17th century, replacing earlier Han styles of clothing such as the Hanfu. The modern term Chinese nation (Zhonghua Minzu) is now used to describe a notion of a Chinese nationality that transcends ethnic divisions.
• Languages
Most languages in China belong to the Sino-Tibetan language family, spoken by 29 ethnicities. There are also several major linguistic groups within the Chinese language itself. The most spoken varieties are Mandarin (spoken by over 70% of the population), Wu, Yue (Cantonese), Min, Xiang, Gan, and Hakka. Non-Sinitic languages spoken widely by ethnic minorities include Zhuang (Thai), Mongolian, Tibetan, Uyghur (Turkic), Hmong and Korean.
Classical Chinese was the written standard in China for thousands of years, and allowed for written communication between speakers of various unintelligible languages and dialects in China. Written vernacular Chinese, or baihua, is the written standard based on the Mandarin dialect and first popularized in Ming dynasty novels. It was adopted with significant modifications during the early 20th century as the national standard. Classical Chinese is still part of the high school curriculum and is thus intelligible to some degree to many Chinese.
