Does anyone know how Minnan dialect came from?

Minnan dialect, also called Heluo dialect, I only know that there are two versions:

One: Heluo dialect was originally the official language of Shang Dynasty. When the Shang Dynasty spread, it was destroyed by Xidi nationality (namely Zhou nationality). The upper-class businessmen who stayed in Heluo area were forced to move to Luoyi as slaves, and the lower-class people were assigned to Wei, Lu and Qi as serfs. The few tenacious businessmen who survived in the east had to return to Jiangnan to develop industry and commerce with rich resources, while those who lived in the southeast coast formed descendants of the Yue nationality.

Two: The origin of Minnan dialect is in the Yellow River and Luoshui Valley, commonly known as "Heluo dialect". This is because in the Western Jin Dynasty, the eight surnames of Lin, Huang, Chen, Zheng, Zhan, Qiu, He and Hu in the Central Plains moved south to avoid war, settled by the unnamed river, and named this river "Jinjiang" to show that it came from the Jin Dynasty. This also brought Heluo dialect to Fujian and evolved into three dialect families: northern Fujian, central Fujian and southern Fujian. After emigrating to Taiwan Province Province, Minnan people brought Minnan dialect to Taiwan Province Province. Unexpectedly, the place where Heluo dialect was originally spoken no longer speaks Heluo dialect.

In addition, about the source of Beijing dialect:

The current Beijing dialect is the result of the change of Chinese tone after the Five Chaos, which is influenced and oppressed by the political and military forces of the northern Hu people. During the Southern and Northern Dynasties, the rulers of the Northern Dynasties used Xianbei as the national language of the Northern Qi Dynasty. After the Tang Dynasty, during the Five Dynasties and Ten Kingdoms period, a large number of Hu people moved to the Central Plains, and Hu and Han people in the north married, and the tone grammar became more and more intense. By the Southern Song Dynasty, the Central Plains had become the world of "Hu Chinese", in other words, variant Chinese had been finalized. Three generations of Liao, Jin and Yuan dynasties all took Beijing as their capital, and Beijing Mandarin gradually took shape. When Cheng Zu moved to Beijing in the Ming Dynasty, Beijing dialect had become the most Hu-hua branch of the Chinese family. After Manchu entered the customs, although Manchu learned Chinese, it turned Beijing dialect into Mandarin for Manchu adults, which westerners called Mandarin. Compared with the Chinese in the Tang Dynasty, the Chinese in the Qing Dynasty is completely unformed, with different tones and different meanings of Chinese characters.

It is really the sorrow of China people. Orthodox Chinese (Heluo Hanyin) is ridiculed by ignorant people as a vulgar dialect. It is even more deplorable that the Han people insulted their ancestors' language without knowing it. This is a linguistic recognition that the thief is the father.
