Who invented Minnan dialect?

The formation of Minnan dialect is mainly due to three waves of immigrants, and the reason of immigration is to recruit barbarians and avoid chaos:

The first time: Jin people moved to Fujian in the fourth century → the formation of Quanzhou dialect.

During the Luanhua phio5 of the Western Jin Dynasty (304-439), aliens invaded the Central Plains and stayed in Yongjia for two years (308). The "Eight Dressed Families" of the Central Plains (Huang Lin, Chen Zheng, Zhan Qiu and He Hu) began to take refuge in Quanzhou, Fujian Province. They loo3 (hiu3 ancient Chinese at that time (such as body, bride, injustice, chopsticks and rudeness) as a result.

The second time: In the 7th century, the fathers of Zheng Chen and Chen Yuanguang settled in Zhangzhou, forming Zhangzhou dialect.

In the second year of Tang Gaozong (669), there was a "savage commotion" between Quanzhou, Fujian and Chaozhou, Guangdong. The imperial court sent Zheng Chen and Chen Yuanguang from Gushi, Gwangju, Henan Province (that is, Gushi County, Xinyang City, Henan Province, near Anhui Province) south to quell the chaos. After the chaos, they stationed troops in Zhangzhou, followed by military forces. In other words, they brought medieval Chinese in the seventh century.

The third time: in the ninth century, Wang Chao, Wang Shenluan and Wang (also from Gushi, Gwangju, Henan) ruled Zhangzhou → the formation of Zhangzhou dialect.

At the end of the Tang Dynasty, the "Huang Chao Rebellion" occurred in China (878), and the court sent Wang Chao, Wang Shenluan and Wang San, brothers from Gushi County, Henan Province, south to put down the rebellion. After the rebellion, Wang Chao was appointed as the special envoy of our army in Fujian. That is, Pi Renge brought Chinese people from the Central Plains in the ninth century.

Most of these two groups of immigrants came from Gushi, Gwangju, Henan. They taught Fujian people to read the Four Books and Five Classics in Gushi dialect, which later became "Zhangzhou dialect" and was the main source of "pronunciation". Yi preserved the sound of reading in the Tang Dynasty.

At the end of the Ming Dynasty, scholars systematically sorted out the Minnan dialect at that time, and wrote "A Treasure Mirror of Yin Hui", which gave birth to fifteen tones.
