Where is the real birthplace of Cantonese?

Cantonese is not a native product of ancient Guangdong, but a product of the combination of Central Plains language and local language. Since the Qin and Han Dynasties, a large number of Central Plains immigrants came to Lingnan along the traffic line of Xiaoshui-Heshui ancient road, settled and multiplied in the middle reaches of Xijiang River, and preserved the ancient Chinese of Central Plains from which they came. Today's Fengchuan dialect still retains the voiced initial system of ancient Chinese, which is unique to Cantonese at all levels in Guangdong. Examples of Fengchuan dialect: [b] break the capital [d] tens of thousands of Tao Dong [g] Ge Genkui * * *, including the ancient voiced consonants of Qieyun and the ancient voiced consonants of Bang, Duan and Jian in Qing Dynasty. Ancient vowels and bang vowels are pronounced as [b], and ancient vowels and vowels are pronounced as [d]. Therefore, the ancient hills, tails and vowels in Qieyun are all pronounced as voiced stops, which are integrated with ancient, definite and group vowels. Experts believe that before Qieyun, from the Han Dynasty to the Southern Dynasties, Central Plains Chinese had been introduced into Fengchuan, and gradually deviated from the development track of Central Plains Chinese, forming a dialect. One of its manifestations is that its voiced initials have not been "purified". Therefore, from today's Fengchuan dialect, we can see some characteristics of early Cantonese, which is the direct evidence that Cantonese originated from Fengchuan dialect, so Fengkai is the birthplace of Cantonese.
