The ancient Indo-Europeans were a primitive people who lived on the Ukrainian plain in eastern Ukraine and southern Russia about 6,000 years ago. They are the common ancestors of Europeans and Indians today. Relying on two big rivers, the Volga River and the Don River; Suitable climate, abundant aquatic plants and flat terrain are the main conditions for their migration.

Around 2000 BC, an Aryan of the ancient Indo-European language family crossed the Urals from the Eastern European Plain to the Afghan Plateau, and one of them went south to the Punjab Plain in the Indus Valley. The other is in the opposite direction, heading west into Iran.

By the 6th century BC, after 65,438+0,000 years of continuous migration and war, Aryans had extended their territory to the whole of northern India, the Himalayas in the north, the Indies in the south, and the sea in the east and west.

On the Afghan plateau, an ancient Indo-European once crossed the towering green hills (now Karakorum Mountain) and the Tarim Basin with yellow sand everywhere, and came to the Qilian Mountains in Gansu, China today. For the first time in history, a connection was established between the ancient Indo-European language and the splendid China civilization. They were called "Big Moon Family" in China ancient books and were expelled by Xiongnu. Their leader was hacked to death by Attila, and his head was made into a hip flask. Later, it was extinct by the Han people, and it was also called Tuholo people in the west.
