Is Cantonese brought from Henan?

Elegant language from the northern Central Plains and Chu language from the State of Chu.

Yiya language: Cantonese is a language that originated in the northern Central Plains, spread to Guangdong and Guangxi during the Qin and Han Dynasties, and merged with the local ancient Vietnamese.

Elegant speech was originally the official language of the Zhou Dynasty, and Confucianism took elegant speech as the carrier from the day of its birth. Confucius taught with elegance, emphasizing that "poetry and calligraphy should be polite".

After Qin unified Lingnan, 500,000 people moved from the Central Plains, and the elegant words brought by immigrants became the earliest source of Cantonese.

Erchu Dialect: Li Xinkui, a linguist, believes that "the earliest source of Cantonese should be the result of Chu people moving south and Chu dialects coming south" (Li Xinkui's Guangdong Dialect).

Historical evolution: From the Han Dynasty to the Tang and Song Dynasties, people from the Central Plains migrated to Lingnan continuously, which promoted the development and stereotypes of Cantonese.

In the Yuan Dynasty, Mongolians moved their capital to Dadu (present-day Beijing area) in units of sixteen states, and took the local dialect as the official language. At that time, the differences between the Central Plains language and Middle Chinese and Cantonese were increasing: the Central Plains language at that time developed rapidly in the direction of Beijing Mandarin.
