There were many theories about the ancestors of the Dongyi people. According to historical records, the ancestors of the Dongyi people could be traced back to Taihao. Taihao was a descendant of Fuxi and was also known as the East Emperor or the Green Emperor. Another theory was that the ancestors of the Dongyi people came from the Caucasians in southern Europe, the Tunguska people in the Siberian jungle, and the mixed-blood descendants of the Pacific Polynesian islanders.

The origin of the Dongyi people could be traced back to the pre-Qin period of China, especially during the Shang and Zhou Dynasties, when the residents of the Central Plains referred to the residents of the lower reaches of the Yellow River. According to archeological research, Dongyi referred to the carrier of the Hou-Li culture and the Yueshi culture. During the Eastern Zhou Dynasty, after many years of management by Qi, Lu and other countries in Shandong, Yi and Xia gradually merged. The Dongyi culture was one of the oldest civilizations in the pre-Qin period of China. The Dongyi people were the creators and users of the oldest characters, bows, rituals, and metals in China. However, there was still some controversy and uncertainty about the specific origin of the Dongyi people. The current research had not yet given a definite answer.
The features of the ancient Dongyi people included yellow skin, black hair, eyes, medium build, and flat face. The features of Dongyi people in Shandong were high nose bridge, deep eye sockets, triangular eyes, high cheekbones, big lips, and thick body structure. The Dongyi people looked similar to the legendary dragon, so some people thought they were the descendants of the dragon. In addition, the appearance of Dongyi people was related to the variety of ancient China appearances. Generally speaking, Dongyi people's appearance might be different in different regions, but they could be generally described as yellow skin, black hair, eyes, medium build, and flat face.
Dongyi people were originally referred to as the tribes in the eastern part of Henan Province, Shandong Province, and the northwest part of Jiangsu Province (Xuzhou City). Later, Dongyi expanded to include residents of Northeast China, the Korean Peninsula, and Japan. In the Qing Dynasty, it even included the inhabitants of the Polynesian Islands in Oceania and Mexico in North America. Therefore, Dongyi people could be said to be people from Henan, Shandong, Jiangsu, and other places.
The Han people in Yunnan were not indigenous. Their ancestors had migrated from other places in different historical periods. During the Qin Emperor's period (221 - 217 B.C.), the Wuchi Road was built and officials were set up. Some officials settled down along the way in Yunnan. They were probably the first batch of Han immigrants. During the Three Kingdoms, the Eastern and Western Jin Dynasties, the Northern and Southern Dynasties, and the Han Dynasty, the immigrants developed into the "Nanzhong surname". In order to realize the rule of Yunnan, the Shu Han, Eastern Jin, Song, Qi, Liang, Chen and other political powers relied on the Han people's Nanzhong surname and Yi Shuai. During this period, the national characteristics of the Yi and Han merged. During the Yuan Dynasty, some Han people entered Yunnan with the Mongolians and Hui people, such as Yuxi and Tonghai. In the early years of the Ming Dynasty, Zhu Yuanzhang sent generals to lead more than 300,000 troops into Yunnan. After the peace was settled, the army stayed behind. After that, there were many immigrants, and the number of immigrants reached 1.5 million. These immigrants, mainly Han people, were distributed in Kunming, Chuxiong, Qujing, Baoshan, Yuxi and other vast areas. After the Qing Dynasty, more Han people entered Yunnan to do business, survive, and develop. There were many ethnic minorities in Yunnan, and different ethnic minorities had different origins and development processes. For example, the Mongols in Yunnan were formed after Kublai Khan sent the Mongolian army to conquer Dali in 1253, and some Mongolians moved to Yunnan. The Hui people in Yunnan were gradually formed when the Mongolian army conquered Dali and established Yunnan Province. The "original" of the A, Mang and Jiang surnames in Baoshan area were the descendants of the Khitan who followed the Mongolian army into Yunnan. In short, the ancestors of the Yunnan people were complex and diverse, including the Han people who migrated from other places in different historical periods and the ancient ethnic groups of the local ethnic minorities.
