 Hakka is not mutually intelligible with Yue, Wu, Southern Min, Mandarin or other branches of Chinese, and itself contains a few mutually unintelligible varieties.It is most closely related to Gan and is sometimes classified as a variety of Gan, with a few northern Hakka varieties even being partially mutually intelligible with southern Gan.There is also a possibility that the similarities are just a result of shared areal features.
