How were the kings of the vassal states of the Zhou Dynasty named

The relationship between monarchs, ministers and vassals.
The vassal states are not completely independent countries. They are [canonized] by the Emperor of Zhou. The Emperor of Zhou is the common master of all vassal states. That is, the capital of all vassal states. He is the [Minister] of the Emperor of Zhou.
The monarch of the vassal states is the [King] of his own country, and at the same time he is the [Minister] of the Emperor of Zhou.
例如，齐国的第一位君主是姜子牙，他是周文王和武王的谋士。楚王的祖先也是周成王的大臣。
注意，当时【“国家”的概念和今天不一样。他指的是诸侯、国王的“领地”和“封地”。作为齐楚王，作为“一国之王”，他的权力只在他的“领地”之内。周天子有【天下】。也就是说，诸侯代表周天子掌管天下四角。
由于当时生产力水平低下，周王无法直接统治边远地区。比如，齐国田地里收割庄稼，运回周国，可能需要好几年才能到达京城。中央向齐国拨款也需要数年时间。天高皇帝远，没有办法，只能任命诸侯在地方上自治。但诸侯的领地仍然属于【周天子】，周天子可以夺取诸侯的领地和爵位。各地诸侯国必须定期觐见周天子，进贡。
周天子初征诸侯国时，总共分封了七十多个诸侯国，其中有五十多个是【季姓诸侯】，即周天子的同宗亲戚。其余的都是商朝及以前的开国功臣和贵族。姬姓诸侯是用来【以诸侯保周朝】的。即保护【周王室】、【监视异姓诸侯】、【防范少数民族】。
然而，经过多年的发展，周王室不断衰弱，诸侯国不断兼并扩张。特别是西周灭亡后，周王室的合法性和权威受到威胁。
