The middle and lower reaches of the Yellow River-Yangtze River, Indus Valley and Mesopotamia Plain in Asia have formed the cradle of three civilizations due to different geographical conditions. What are the similarities and differences between their cultures? Mesopotamia was divided into two parts, Babylon in the south and Assyria in the north. Today, the two river basins are equivalent to today's Iraq.

The earliest inhabitants of the civilized era in the two river basins were Sumerians. They came here before 4000 BC. They established the initial civilization of the two river basins. Akkadians, Babylonians (Amorites), Assyrians and Chaldeans belonging to Semitic languages inherited and developed the achievements of Sumerians, making the civilization of the two river basins an important page in the history of human civilization. Among them, the Babylonians made the greatest achievements, so the civilization in the two river basins is also called Babylonian civilization.

The civilization of the two river basins originated in the south of the two river basins. Here are the alluvial plains and deltas of the two rivers. Like the Nile in Egypt, these two rivers flood regularly, rising and falling. Only by building dams, ditches and beams to store water and drain water can people cultivate and harvest. Residents in the two river basins mainly use cattle and donkeys to pull wooden plows, and the most important crops are barley and dates. Indus civilization includes two big cities, Harappa and Mohenjo-heroes of the legal world, and more than 100 small towns and villages. Fiona Fang, two big cities, is more than 5km (3 miles) in length, so it can be inferred from its scale that it is the political center of two big countries or a great empire with two cities as its capital in turn (there is a system of one country and two capitals in Indian history), but it is also possible that Harappa became the capital after Mohenjo, a legal hero, because Mohenjo, a legal hero, was destroyed by floods more than once. In Katiyawa and the southern cultural area further south, it developed a little later than the main Indus region. This culture has characters, about 250 ~ 500 characters, some of which have been tried to be explained, and this language is temporarily classified as Dravidian. The central period of this civilization is about 2500 ~ 1700 BC, but the culture of the southern region that appeared before 2000 may last even later. The Yellow River civilization originated in Yuanqu Basin and is widely distributed in the middle and upper reaches of the Yellow River. Taking painted pottery as a typical object, it spans the farming culture of matriarchal clan society and paternal clan society. It was first discovered in Yangshao village, the platform on the south bank of the Yellow River in Mianchi, Henan Province, and is called Yangshao culture. About 8000 to 5000 years ago. It exchanged and merged with Liangzhu culture, Hemudu culture, Wushan Daxikou culture, Shandong Dawenkou culture and Qijia culture, which later originated in the middle and lower reaches of the Yangtze River, in Gan Qing, forming a wider range of Longshan culture and Xia, Shang and Zhou culture, which is today's Chinese civilization. Its distribution area is over 800,000 square kilometers, which is twice that of ancient Egyptian civilization, Mesopotamian civilization, Greek civilization and Indian Ganges civilization combined. It is the only prehistoric culture in the world that has been passed down to today through language.
