Mandarin

Mandarin is the largest branch of the Sinitic languages. Mandarin varieties are natively spoken by 70 percent of all Chinese speakers, spread over a large geographical area that stretches from Yunnan in the southwest to Xinjiang in the northwest and Heilongjiang in the northeast. Its spread is generally attributed to the overall greater ease of travel in the North China Plain compared to the more mountainous south, combined with the relatively recent spread of northern varieties to frontier areas. Many varieties of Mandarin, such as those of the Southwest and the Lower Yangtze, are not mutually intelligible with the Beijing dialect. Nevertheless, Mandarin as a group is often placed first in lists of languages by number of native speakers. Because Mandarin originated in North China and most Mandarin varieties are found north of the Yangtze River, the group is sometimes referred to as Northern Chinese.
