What is the difference between Chaozhou dialect, Shantou dialect and Jieyang dialect in Chaoshan dialect?

Shantou, who lived in Chenghai Chaozhou as a child, is now studying in Chaoyang. I have a deep understanding of the languages in these areas, and it is no problem to switch pronunciation and intonation seamlessly in one second. Supporting the previous statement, Shantou people think Shantou dialect is the most standard. But in fact, with the transfer of rural population to cities and the transformation of towns, it is difficult to find the so-called standards. Based on the language of Shantou city, Chaoanbu dialect in Chaozhou has a high tone and many nasal sounds, which is very similar to Chenghai dialect, while Jieyang dialect is similar to Chaozhou dialect, but its tone is relatively flat. To sum up, what sounds nothing is Shantou dialect. Chaoyang dialect, Chaonan dialect and Shantou Chaozhou dialect are quite different, so many people in Jieyang, chaozhou people and Chenghai can't understand Chaozhou dialect. Shantou will understand, because it is close to Chaoyang. Chaoyang dialect and Chaonan dialect also have certain stress division in the region. For example, if I listen to my brother-in-law Haimen, I will feel more seafood ... This is really indescribable. Unfortunately, Zhihu has no voice function. I don't know much about South Australia. According to local students, it is the same as Shantou dialect. Nowadays, Chaozhou operas are basically like Chaozhou dialect, which may be due to the singing. Later, I will analyze the accents of several hosts of Shantou TV Station in detail … As for Shanwei … Shanwei does not belong to Chaoshan area. Generally, we become the "Shanwei three-zone synthesis" of Hailufeng. Although it is closely related to the name of Shantou, the development of Shanwei itself is not close to Shantou, and Shanwei locals are also disgusted with Shantou. See Shanwei Plate on Zhihu for details. Every region of Chaoshan dialect has its own characteristics, so it may be necessary to consider where this accent belongs. After all, this accent has environmental factors and its own variation when learning a language.
