In West Asia, the Euphrates and Tigris rivers flow into the Persian Gulf from north to south. They are like twin brothers with different tempers and personalities. The Euphrates River is gentle and gentle, flowing slowly from north to south. The Tigris River is grumpy and willful. The alluvial plain in the lower reaches of the two rivers is called Mesopotamia, which means between the two rivers in Greek. Westerners call it the fertile moon belt because it looks like a crescent moon. We also call this area the two river basin area. Today's West Asia has become a rich region because it is rich in oil. At the beginning of human civilization, West Asia had to travel around because of lack of resources and materials. Surprisingly, the first dawn of human civilization rose in this land, where the earliest characters in the world were produced and the earliest cities in the world were established.

Both the Euphrates River and the Tigris River originate from the mountains and highlands in eastern Turkey, and then flow southward almost parallel to the Persian Gulf. The alluvial plain formed along the two banks is Mesopotamia. Mesopotamia, as one of the main cradles of human civilization, produced the earliest human civilization from 4000 BC to the 2nd century BC, so it was called "Two Rivers Civilization" or "Mesopotamian Civilization".
