In fact, the autosomes of ancient Han people were far north. Judging from the remains of the ancients and two Han armies in Wadian, Yuzhou, Henan Province, it is close to the level of Koreans, even farther north than the present northern Han people. In fact, the ancient Han people were not Hu Chinese, but from the south of China, and the modern Han people were more influenced by the southern ethnic origin than Hu people. According to historical records, the Guangfu nationality was a mixture of Han Chinese and South Vietnamese who moved southward during the Qin Dynasty. It was 2K years old in the Qin dynasty, so it is a bit unreasonable to say it is a "guest". Hakka moved south in the middle of Qing Dynasty (initiative+government promotion). At that time, they were refugees, and the Taiping Heavenly Kingdom, with Hakka as the main force, was unpopular at that time. There is nothing wrong with Hakka saying "guest"
The concept of Guangfu people only came into being in recent decades, because people in western Guangdong are fundamentally different from those in the Pearl River Delta. Long-term hybrids in the Pearl River Delta have no indigenous concept at all. For thousands of years, Arab Persians and wealthy families in the north have taken refuge in the Pearl River Delta. And there must have been many foreigners in Guangzhou before. In the Tang dynasty, the Arab population accounted for one-third and was finally slaughtered. Many refugees took refuge in the suburbs of the Pearl River Delta. In Song Dynasty, Yuan Dynasty and Ming Dynasty, maritime silk. Many people in the Pearl River Delta actually have many eyes with high nose, double eyelids and cheekbones. I have been in Foshan, Guangzhou for five years, and I have seen too much.
Before the Song Dynasty, although Guangzhou Port was prosperous at that time, the whole Pearl River Delta was not as developed as northern Guangdong. Because northern Guangdong borders Jiangxi and is the throat of the north-south fortress, the population is relatively concentrated. Before the Song Dynasty, northern Guangdong was ahead of the Pearl River Delta in economic and political status. In addition to Guangzhou Port at that time, the Pearl River Delta was still a water town with marshes everywhere. After the Song Dynasty, due to a large number of people moving south, productivity and production technology also moved south, and northern Guangdong slowly fell behind the Pearl River Delta, and later became an underdeveloped area, the Pearl River Delta really began to develop.
The Han nationality in the south of China is descended from the yellow race in different regions (now the minority in the south), but it is rare, and the descendants of each province are different. Moreover, most of these ethnic minorities are of the same ancestry as the Han nationality, which is different from the same group of yellow people who moved to China. That is, Altai people in Northeast Asia, such as Manchu, are all of short and black descent (because East Asia was short and black before, but it was slaughtered and expelled by our ancestors).
Guangfu people themselves can be divided into three factions: one is the western Guangdong faction, and the other is the northern Guangdong faction of the Pearl River Delta faction. They don't know the so-called Cantonese. In particular, people from the Pearl River Delta can understand your Pearl River Delta accent when they travel to western Guangdong and northern Guangdong, while people from western Guangdong and northern Guangdong can understand Cantonese of people from the Pearl River Delta. As long as you travel there with a Pearl River Delta accent, you will only be slaughtered.
