The characters in Minnan dialect have the same pronunciation and meaning as those in ancient Chinese. Is it ancient mandarin?

Why is the reference Taiwanese (Minnan dialect) also called "Heluo dialect" or "Zhongyuan ancient sound"? There are many explanations about "Heluo dialect", and the most popular one is the meaning of "Luoyang dialect in Henan". Luoyang has long been the capital of China's ancient dynasty, and the "Heluo dialect" here is equivalent to the official language, such as Mandarin today. In ancient times, Minnan was called "the land of barbarians" or "the land of savagery", but it also had its own aborigines. In the Tang Dynasty or earlier, due to the rise and fall of dynasties, the old dynasties were often forced to flee to remote southern Fujian. Therefore, their language was brought into southern Fujian. Moreover, because the indigenous people in southern Fujian were not dominant in the competition, the language of the Central Plains developed rapidly at that time, so Minnan dialect retained a lot of pronunciation and semantics of ancient Chinese. According to textual research, the folk language of the Tang Dynasty is now "Minnan language", so in a sense, poets such as Li Bai and Du Fu can speak Minnan language. All these can be reflected in their poems, which is why there are more rhymes in Minnan when reading Tang poems. So it is also called "the ancient voice of the Central Plains". Let me add one more point here. Now our Mandarin is based on Beijing dialect. When did Beijing become the capital? That's right, Yuan Dynasty. Prior to this, Beijing has always belonged to the frontier. Isn't the Great Wall of Wan Li evidence? Nowadays, Beijing dialect is a blend of many local languages, especially in the Yuan and Qing Dynasties. Influenced by ethnic minorities, Beijing dialect is more inclusive and diverse. Therefore, Beijing dialect is the fastest changing language in a certain period. So now reading some ancient books in Putonghua will have some differences in pronunciation and meaning. /view/3324 1.html？ weight
