What are the similarities and differences between the internal and external clothing system of Shang Dynasty and the enfeoffment system of Western Zhou Dynasty?

The internal service is the activity area of the merchant's own family, and the external service is a country outside the merchant's family. Shang Wang handled the affairs of his family and surrendered foreigners through two different management systems. As a result, the Shang king controlled the actual power of the alliance and formed a dominant and dominated relationship with other countries. However, the control of the Shang king over the participating countries of the alliance is limited. Countries have basically maintained their original social structure, and they have great autonomy except their obligations to the Shang king. In other words, the relationship between the central and local governments in Shang Dynasty was not maintained by the direct personnel control between the central and local governments, but by the way that local tribal countries established a covenant with the central government under the powerful military power of Shang Dynasty, which is what Qian Mu said: "The princes admitted that the emperor was the son of heaven".

The enfeoffment system in the Western Zhou Dynasty was completely different. It is through direct dispatch of personnel, the establishment of military strongholds, and the direct rule of the local area by the way of "the emperor sealing the princes". Of course, this is a fundamental change in the way the country is governed. With the regional characteristics centered on the capital and the personnel characteristics centered on the relatives, the blood boundary of the old kingdom in Shang Dynasty was broken by the blood of Zhou family, which formed the blood political characteristics from scattered blood to unified blood, thus forming a closer and clearer political relationship between the central and local governments.
