Many people have answered this question before. In the past, Guangxi and Guangdong merged as an administrative region. It was called Guangxin House in the Han Dynasty, and later it was renamed Guangnan House in the Song Dynasty. The big name of Guangdong and Guangxi was Guangnan, and its resident was now Wuzhou City, Guangxi. In the east, Guangdong was called Guangnan East Road, and in the west, it was called Guangnan West Road, which was called Guangdong and Guangxi for short. This earliest name has been used until now. People in Guangxi, Guangdong are also called Guangfu people, and Guangzi. In fact, the earliest Cantonese came from Wuzhou. Guangxi is called vernacular, and Cantonese is called Cantonese, which are all different names of a language. Later, there were some new ideas about the division of Guangdong and Guangxi. For example, some people thought that it was based on the 100,000 mountains on the border of Guangdong and Guangxi, with Guangdong in the east and Guangxi in the west. Among the Zhuang people, 100,000 was an interpretation sound, meaning that it was tall and could reach the sky. 100,000 was not a number, but an interpretation sound. At that time, Guangxi included Zhanjiang and Hainan Island now. The last idea was that Hunan Province was not called in the Song Dynasty. Nowadays, many people in northern Guangdong still refer to Hunan as Huguang, and the eastern part of Huguang is Guangdong. Later, people from other provinces came to call us Guangdong, and the eastern part of Huguang and the western part of Huguang are called the western part of Huguang, which is called Guangxi for short. These are not unreasonable. Thanks for your attention.
