Jin (simplified Chinese: 晋语; traditional Chinese: 晉語; pinyin: jìnyǔ) is a variety of Chinese spoken by roughly 63 million people in northern China, including most of Shanxi province, much of central Inner Mongolia and adjoining areas in Hebei, Henan, and Shaanxi provinces. Some "non-core dialects" currently classified as Jin is heavily contested by linguists to reclassify them as dialects of Mandarin.
