Ganzhou is the cradle of Hakkas and one of their base camps, but the dialect in downtown Ganzhou is not Hakka. This is mainly because Wang Yangming, a former official of Ganzhou, brought Liuzhou dialect in Guangxi to Ganzhou, making the whole Gannan area a Hakka dialect area except the urban area. I am an authentic Hakka in Gannan. I think it's about this!
