Should Cantonese be cantonese? Or should it be in Wuzhou dialect (or Zhaoqing dialect)? First of all, you have to figure out the source of Cantonese.
"Yue" through "Yue", the vast land from Vietnam to Jiangsu and Zhejiang in ancient times, is a Baiyue ethnic settlement, located in the Liangguang area of Lingnan inhabited by many Baiyue ancestors. After the Sui and Tang dynasties, "Cantonese" became a single reference to Guangdong, and the northeastern coastal area from Fujian to Jiangsu and Zhejiang was called "Yue", so Cantonese definitely referred to Cantonese specifically.
After the Unification of China by the Qin Dynasty, the Han Chinese in the Central Plains began to migrate south to Lingnan in small numbers, and a large number of them began to move south from the Yiguan Nandu of the Eastern Jin Dynasty, in addition to avoiding war, the Five Dynasties and Ten Kingdoms and the Southern Song Dynasty were also the peak of migration, they lived with the local Baiyue people and intermarried, and also brought the Culture and Language of the Central Plains. Therefore, Cantonese is actually a combination of the Central Plains Mandarin and the Baiyue language, retaining a lot of ancient sounds, as can be seen from the fact that reading poems in Cantonese rhymes much more than Mandarin.
According to historical research, the first Central Plains people to enter Lingnan were non-commissioned officers of the Qin Dynasty, who were distributed at that time in the area where the two cantons meet, that is, Zhaoqing in Guangdong or Wuzhou in Guangxi, and are generally believed to be the birthplace of Cantonese.
However, with the establishment of Nanhai County, Guangzhou began to become the central city of Lingnan, and has been the political, economic, transportation and cultural center of Lingnan for more than 2,000 years. Therefore, the current Cantonese must be based on Guangzhou dialect, just like Mandarin is based on Beijing pronunciation.
In fact, there is guangxi where Cantonese is spoken, and from the distribution point of view, it is obvious that it radiates out of Wuzhou, which can confirm that this is the origin of Cantonese. However, the same language, not to mention the province and city, even the next village may have different tones, which is the so-called regional dialect.
