Is Wengyuan Hakka difficult to learn?

Wengyuan Hakka dialect can be divided into four categories: Guilin-Longxian in the north of Wengyuan is a Hakka dialect system, and Zhoupi and Xiaxia are a system. Sanhua, Liuli and Songtang Nakamura are a system. Songtang, Jiangwei and Bazi are a system, and Guandu and the lower part of Miaodun are a system. Wengcheng, Xinjiang, Hongling and so on are a system. But the origin of Hakka dialect is based on Meizhou Hakka dialect. In other words, when Mandarin is converted into Hakka, you can basically learn Wengyuan's Hakka by learning Meizhou's Hakka. good luck
