The oldest Huizhou is the most primitive nation in Guangdong. At the beginning of Guangdong's development (probably before the Qin Dynasty), the local ancient Huizhou dialect did have a chance to compete with the vernacular. However, the original cultural system in Huizhou was disrupted by Zhao Tuo's entry into Guangdong. In the final competition, the ancient Huizhou dialect lost power, and the vernacular became the standard official language-Cantonese, which is also a strong language in the world.

Huizhou dialect did not stop because of losing power, but became weaker and weaker because of the influx of northerners. Because these guests have no household registration and can only occupy the hills, they are listed as Hakkas by the government. The word "Hakkas" first appeared in Huizhou.

Hakka people merged with some local people and gradually developed Huizhou local Hakka dialect, such as Huiyang Hakka dialect and Huidong Hakka dialect.

In the end, Huizhou became a Hakka area, and the original environment of Huizhou dialect was squeezed into the coastal areas of Dongjiang River.

People in Chaoshan area also settled along the coast of Guangdong by fishing, so a few people in Huidong were gradually influenced by it, and Xuelao dialect was derived.

Later, Huizhou became the prelude to reform and opening up, and a large number of northerners went south again, forming new Hakkas. These northerners settled in Huizhou, but at this time, Hakka dialect and Huizhou dialect are no longer strong languages, and Huizhou dialect has even faded, and the official has vigorously promoted Putonghua. Therefore, a new generation of Huizhou people gradually abandoned their original hometown dialect and switched to Mandarin.
