Do Sichuan old people in Dongfang City, Hainan communicate with language bears?

You asked whether Sichuan dialect can be exchanged in Hainan. No, Sichuan dialect is very different from Hainan dialect.

About 3000 years ago, a branch of the ancient Baiyue nationality crossed the Qiongzhou Strait from Guangdong and Guangxi to Hainan Island, which is the ancestor of today's Li nationality. At the end of the Southern Song Dynasty, hundreds of thousands of Fujian Putian, Quanzhou, Zhangzhou and chaozhou people immigrated to Hainan Island, bringing with them the ancient Minnan dialect, Minnan culture and Chaoshan culture, which promoted the formation of Hainan dialect.

Later, Han, Miao, Hui and other ethnic groups moved to Hainan one after another, gradually forming a multi-ethnic settlement in Hainan today. After historical evolution, some characteristics of all ethnic groups have been assimilated, but dialects, as the most basic characteristics of ethnic groups, have been preserved and passed down from generation to generation, forming many Hainan dialects today, among which Hainan dialect is the most widely used.

Hainan dialect has a very complete set of grammar and pronunciation, which is rare in the pronunciation system of Putonghua and various local dialects in China (the exclamation mark "tut" is an exception in special circumstances).

For outsiders, sonic booms need serious study and training to master. Because this means that in the process of pronouncing a syllable, it is very difficult to inhale briefly and then exhale. It's hard to master, not since childhood.
