In the sixth year of Emperor Ding Yuan of the Han Dynasty (1 1 1), it was also a major military action to destroy Yue. From the Three Kingdoms to the Western Jin Dynasty and the Eastern Jin Dynasty, frequent wars in the Central Plains forced a large number of Han people to move south, and many of them came to Guangdong and Guangxi one after another. The war in the Yuan Dynasty also prompted a large number of Han people to go south. During the Ming and Qing Dynasties, the number of Han people entering Guangdong and Guangxi increased.
The vernacular was originally a dialect formed by the Han people in the Central Plains when they went south to Guangdong. In order to do business along the Xijiang River, Cantonese settled in Nanning, so Nanning had a vernacular. Guangdong vernacular was formed late. Nanning in the Ming Dynasty was very small, with Pinghua as the main city and Mandarin as the main government office. At this time, the power of vernacular is still very small. In Qing Dynasty, Xiakuo Street Mandarin was a dialect widely used in Nanning. Later, more Cantonese moved westward, Nanning gradually became the world of vernacular, Pinghua retreated to the suburbs, and Xiakuo Street Mandarin was "compressed" to one or two streets. The vernacular in Guangxi is closely related to Cantonese. Nanning and even the vast areas in the south, middle and east of Guangxi (Fangchenggang, Baise, Nanning, Qinzhou, Beihai, Pingxiang, Hezhou, Chongzuo, Wuzhou, Guigang, Yulin and other areas) belong to Cantonese. These areas account for nearly half of the area of Guangxi, and more than half of the population are essentially within the scope of Lingnan culture. Nanning dialect belongs to Yongjiang Cantonese, which is mainly popular in towns with convenient transportation on both sides of Yongjiang and Jiang Xun, such as Nanning, Yongning, Chongzuo, Longzhou, Ningming, Hengxian, Guiping and Pingnan. Although there are some differences between Nanning dialect and standard Cantonese, it is basically no problem to communicate with Cantonese speakers in Guangdong. It can be said that the traditional cultures of Nanning and Guangdong come down in one continuous line, and language is an example.
