where does the emperor rank in ancient china's social hierarchy
Four occupations There were many social groups that were excluded from the four broad categories in the social hierarchy. These included soldiers and guards, religious clergy and diviners, eunuchs and concubines, entertainers and courtiers, domestic servants and slaves, prostitutes, and low class laborers other than farmers and artisans. The emperor—embodying a heavenly mandate to judicial and executive authority—was on a social and legal tier above the gentry and the exam-drafted scholar-officials. Although his royal family and noble extended family were also highly respected, they did not command the same level of authority.
Zhou dynasty K.E. Brashier writes in his book "Ancestral Memory in Early China" about the tsung-fa system of patrilineal primogeniture: "The greater lineage, if it has survived, is the direct succession from father to eldest son and is not defined via the collateral shifts of the lesser lineages. In discussions that demarcate between trunk and collateral lines, the former is called a zong and the latter a zu, whereas the whole lineage is dubbed the shi. [...] On one hand every son who is not the eldest and hence not heir to the lineage territory has the potential of becoming a progenitor and fostering a new trunk lineage (Ideally he would strike out to cultivate new lineage territory). [...] According to the Zou commentary, the son of heaven divided land among his feudal lords, his feudal lords divided land among their dependent families and so forth down the pecking order to the officers who had their dependent kin and the commoners who "each had his apportioned relations and all had their graded precedence""[31]
