What can be seen from the distribution characteristics of Shang Dynasty?

The capital of Shang Dynasty moved from east to west. In the early stage, it was in Bo (north of Shangqiu, Henan Province, south of Caoxian County, Shandong Province, and in Shandong Province), then in Tao (northwest of Zhengzhou, northeast of Xingyang), then in China (north of Puyang, Henan Province, south of Neihuang), then in Xing (Xingtai, Hebei Province), then in Pi (north of Yuncheng, Shandong Province, southwest of Liangshan), then in Yan (Qufu, Shandong Province) and finally in Yin (Henan Province).

The characteristics of migration and distribution in Shang Dynasty can be seen as follows:

1. The capitals are all near the Yellow River basin, which is convenient for water intake and irrigation.

2. All the areas around the capital are plain areas, which are convenient for farming, indicating that it was already a farming society at that time, with agriculture as the main industry.

3. It is concentrated in the areas along the Yellow River in Shandong, Henan and Hebei, indicating that the center of development at that time was the middle and lower reaches of the Yellow River.

4. The Shang people belonged to Dongyi, indicating that Dongyi was dominant in the Central Plains at that time, which directly proved that Dongyi ancestors were also one of the main bodies of the Chinese nation.

5. The frequent migration of Shang Dynasty also showed that the society was unstable and threatened by other nationalities.

6. The gradual migration from the downstream to the upstream shows that the Yellow River was extremely unstable at that time, which easily caused the river to flood and even changed its course frequently.
