What races are there in Xinjiang?

Xinjiang lies in the depths of Asia. People from Africa, Europe and West Asia want to go to East Asia, and they all have to pass through Xinjiang. When people from East Asia go to Central Asia, West Asia and Europe, they also have to pass through Xinjiang, where the eastern and western races have exchanged and merged. As you can imagine, people of all colors spoke various languages at that time. Today, we become a family, and tomorrow they will become a family, constantly carrying out complex genetic exchanges and forming a multi-ethnic group in Xinjiang. Therefore, it is not an exaggeration to call Xinjiang an "ethnographic museum". In his view, Xinjiang in that period was divided into three regions: south, north and east, and there were "immigrants" everywhere. The Europa people of three branches, namely, the ancient European type, the two rivers in Central Asia type and the Mediterranean type, migrated from southern Siberia, Central Asia and other places, or from the Pamirs, while the Mongols migrated from Gansu and Qinghai in the upper reaches of the Yellow River and gathered in Xinjiang from all directions. Xinjiang is full of mixed-race spaces and mixed-race children everywhere. In different regions, the ethnic mixed-race is different in composition, so it is difficult to define whether it is Mongolian or Europa. The earliest and most obvious reflection of this point is the eastern Xinjiang region. From the tomb of Shanpula in Luopu County, Hotan area, it can be seen that Mediterranean people of Europa race lived here from 1 century BC to the 3rd century AD. Judging from the ruins of the ancient city of Loulan, the ethnic groups in Loulan area in the Eastern Han Dynasty seem to be hybrids of Europeans and Mongols, among which the characteristics of Mediterranean Europeans are more obvious. There are also the Niya ruins in Guo Jing in the Han Dynasty, and the Yuan Sha people who are mainly Mediterranean people. However, the mixed blood between the various branches of the Europa race is more complicated. The ancient European type, the two rivers in Central Asia type and the Mediterranean type, some of which first entered the Peacock River basin in Lop Nur, Xinjiang, mixed with Mongolian people and gradually migrated to the east and south of Xinjiang; Some crossed the Pamirs, entered Xinjiang, and then moved eastward slowly along the southern margin of the Tarim Basin, blending with the Mongols. Some have reached the upper reaches of the Ili River and even the Tianshan area in the east.
