<P> There were many similarities between the decentralized systems . When the dynasty was established, the conquered land was divided into hereditary fiefs (諸侯, zhūhóu) that eventually became powerful in their own right . In matters of inheritance, the Zhou dynasty recognized only patrilineal primogeniture as legal . According to Tao (1934: 17--31), "the Tsung - fa or descent line system has the following characteristics: patrilineal descent, patrilineal succession, patriarchate, sib - exogamy, and primogeniture" </P> <P> The system, also called "extensive stratified patrilineage", was defined by the anthropologist Kwang - chih Chang as "characterized by the fact that the eldest son of each generation formed the main of line descent and political authority, whereas the younger brothers were moved out to establish new lineages of lesser authority . The farther removed, the lesser the political authority". Ebrey defines the descent - line system as follows: "A great line (ta - tsung) is the line of eldest sons continuing indefinitely from a founding ancestor . A lesser line is the line of younger sons going back no more than five generations . Great lines and lesser lines continually spin off new lesser lines, founded by younger sons". </P> <P> 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" " </P> <P> This type of unilineal descent - group later became the model of the Korean family through the influence of Neo-Confucianism, as Zhu Xi and others advocated its re-establishment in China . </P>
