Is Daye dialect similar to Hunan dialect?

I don't think so. Daye dialect is different from Hunan dialect. The ancestors of Daye generally believed that it was migrated from Jiangxi after Huguang filled Sichuan and Jiangxi filled Huguang, and the accent was more similar to Jiangxi dialect. Daye city is a county-level city under the jurisdiction of Hubei Province, which is under the management of Huangshi City. It is located in the middle of China, the southeast of Hubei Province and the south bank of the middle reaches of the Yangtze River, with a land span of11431'-1520' and a latitude of 29 40'-30. Located in the hilly area on the northern edge of Mufu Mountain range, the terrain is mainly hilly, mountainous and flat.
