What are the characteristics of the Western Zhou Dynasty and its previous kings or vassal states?

From the results of archaeological excavations, the capital of the Western Zhou Dynasty and its former kings or vassal states has the following characteristics: First, although there are various handicraft workshops with fine division of labor in the city, the population is limited and not dense. In the Spring and Autumn Period, is it still like the Warring States policy? Zhao Ce said, "Although the city is big, it is only 300 feet, and although there are many people, it is only 3,000 people.". Second, a large number of farm tools have been unearthed in various residential sites, and there is still a large area of open space without buildings between residential sites, which is no obvious difference from the village sites outside the city. It can be seen that the residents in the city, like those outside the city, still focus on agricultural production. This shows that it was still in the early stage of urban-rural division of labor. Third, the residents in the city live in scattered places. There are cemeteries with different ethnic emblems in the city, and there are both nobles and civilians in each cemetery. These scenes also show that the tradition of clan organizations and ethnic groups living together still remains. So the city at this time does not have enough economic nature. Strictly speaking, it's just some fortified castles, which have not formed a large-scale and prosperous city.
