Analyses of anthopological, linguistic, and archeological data allow us to form a theory that speculates that the origin of neolithic Proto-Han must be found in the South. We can say that an early neolithic age ethnic in South China, earlier residing at a location bordering the center of the late Hoa Binh Culture, has migrated during the 5th Millenia BC along the Chia-Ling Chiang range in Sichuan and crossed the passes in the Ch'in Ling range to enter the Wei River Valley.
Nature helped them establish and develop quickly agriculture in flooded plains. At the end of the 5th Millenia and beginning of the 4th Millenia, a mid neolithic age ethnic left decorated pottery to be found in Ban Po, a local Yang Shao site. They have aveolar prognathism, with broad noses, indicating clearly a Southern origin.
In the 4th Millenia BC, part of the population moved East along the Yellow River, met in West of Henan people of the Ch'in Wang Chai Culture who migrated there earlier from the Han River Valley. The interaction betwen these two peoples, has created a basis for the founding of the Yin Culture. The language of Yin, based on writings at the end of the 2nd Millenia BC, was Proto-Hua, essentially Sino-Tibetan, though it showed a few traits very different from the linguistic groups within the language family.
The groups that went West in the 4th Millenia BC go through even more transformation. One of these groups arrived to the Upper Yellow River Valley in Gansu, now called Qiang or Jung, whereas another group became the pillar of the Zhou. At the end of the 2nd Millenia, the Zhou defeated the alliance of tribes founded by the Yin in the Central Plains.
This invasion sparked the establishment of many statelets, and with the friction with neighboring tribes speaking Burmo-Tibetan, Proto-Tungusic, Austronesian and Tai, Hua-Hsia appeared in the 6th and 4th Centuries BC in the Central Plains. This can be called Proto Han-Hua.
