Lower Yangtze Mandarin
Lower Yangtze Mandarin (simplified Chinese: 下江官话; traditional Chinese: 下江官話; pinyin: xiàjiāng guānhuà) is one of the most divergent groups of Mandarin dialects, as it neighbors the Wu, Hui, and Gan groups of Chinese varieties.
It is also known as Jiang–Huai Mandarin (simplified Chinese: 江淮官话; traditional Chinese: 江淮官話; pinyin: jiānghuái guānhuà), after the Yangtze (Jiang) and Huai Rivers.
Lower Yangtze dialects are distinguished from most other Mandarin varieties by their retention of a final glottal stop in words that ended in a final stop in Middle Chinese.
