姬姓

据说，周初分封了七十一国，姬姓之国共有53个。

It is said that the Zhou Dynasty enfeoffed 71 small feudal states in the early years , among them 53 states'family names were Ji .

柳姓源于姬姓和展姓，柳下惠为其近祖，秦统一六国时徙居河东。

Clan Liu was originated from Clan Ji and Zhan , with Liu Xiahui as its near ancestor , who moved to Hedong when Qi unified the six countries .

因此周代分封诸侯，把“宗法”与“封建（封候建国）”结合起来的做法，便形成了围绕姬姓宗族的层层“大、小宗”的严密等级关系。

So a strict hierarchy grew up among the feudal lords of the Zhou Dynasty , based on the patriarchal clan system and involving clans to which principal wives and concubines belonged .

而且，曹国虽是小国，但因其是姬姓诸侯国，身为宗室贵胄，在春秋时期的诸侯争霸舞台上倒也扮演了一个不可或缺的角色。

Cao is a small country , but because he was surnamed Chi vassal state , as the imperial clan nobles , also played an integral role on the stage of feudal hegemony in the Spring and Autumn Period .
