What are the similarities and differences between the origins and characteristics of ancient western and ancient China cities? And analyze the reasons.

Comparison of the Origin of China and Western Cities 1) Geophysics and China City 2) Political and Military Embodiment in the Planning of China Ancient City 3) Summary 1. The geopolitics of China and the appearance of cities in China are quite different from those in the two ancient river basins and ancient Greece. The place where China culture originated is called the Central Plains, and the Indus River, the Two Rivers and the Nile River are not as big as China. There is no serious traffic jam in this small world, so in the Longshan culture in the late Neolithic period, the cultures of all adjacent areas are almost the same, and its continuity changes very slowly. On the one hand, there are many centers in the same land that challenge each other, on the other hand, they learn from each other in the comparison of challenges, so the similarities and differences are dialectically combined. As far as materials are concerned, a large area of loess in the Central Plains constitutes a special condition. Loess is not natural and fertile, it depends entirely on human efforts. The long-term improvement and long-term stability of farming areas have resulted in the combination of geographical aborigines and relatives. When villagers in the same place live together for a long time, they become a family, so there is a close relationship outside the aborigines. In addition, the migration pattern in China is to make up for the vacancy, not to migrate for a long time. This feature makes the distance between mother group and daughter group not alienate, and the interdependent relationship can be maintained for a long time. The consequence of the evolution is that a large number of people are inextricably linked under high-density distribution, which is conducive to the formation of large-scale complex political groups. Such an enlarged political group can have no boundaries. The political group is based on the crowd, and the crowd base can share the same surname as the blood base in symbol. For example, Yan Di and Huangdi claimed to be brothers. This combination process is not based on geographical relationship, but on blood relationship. The premise of combination is that several parties are the same family or have a marriage relationship. In China, there is no geographical combination like the two river basins, which changed after the Shang Dynasty. There were two parallel political unit systems in Shang Dynasty, one was a regional city, and the other was a blood clan. The Western Zhou Dynasty won by patriarchal clan system, and the Zhou Dynasty chose to combine people by blood. This choice formed a major feature of China, and the political group expanded by China was expanded by the blood group. Reflected in the vocabulary, there is one family in the world and no family in China. Our expansion can create a cosmic empire, which is based on blood relationship. In social relations, kinship is the gene of all relations. As can be seen from the above description, economic activities played a negligible role in the life of the people in early China, and it did not play a decisive role in the social development of early China. During the Xia, Shang and Zhou Dynasties, according to archaeological data, there was almost no evidence that three generations of cities were the centers of commodity production and circulation. Ancestral temples are often located in the city center and are the core of settlements. The ancestral temple is not only a place for ancestor worship, but also a place for political activities, and a place for exercising administrative power and issuing government decrees. Urban settlement is basically a large-scale settlement centered on ancestral temples and palaces, surrounded by handicraft workshops and agricultural settlements, and it is the religious etiquette center and political center of aristocratic political ruling areas with different levels and positions. During this period, religious activities and political activities were inseparable, and power was exercised by religious activities in the name of religion. The ancestral temple is the center and ruling symbol of the centripetal force and cohesion of the blood organization, the meeting point of etiquette supplies in the name of God, and the center of accumulation, redistribution and main consumption of surplus wealth and social surplus labor.
