Where is the most authentic Cantonese?

The most authentic Cantonese should be Hong Kong, because Cantonese is widely used and is less influenced by foreign accents! ! !

Secondly, Shaoguan (mainly refers to the urban area, because all counties speak dialects, mainly Hakka! ) The relationship between Shao and Cantonese is both the birthplace and deeply influenced by Hong Kong! ! !

Although Guangzhou is the provincial capital, the distance from the ground is mixed with an accent, which sounds terrible! ! !

The above is purely a personal opinion.
