King Kao of Zhou
King Kao of Zhou was the thirty first king of the Chinese Zhou Dynasty and the nineteenth of Eastern Zhou.
His personal name was Wéi. King Kao's father was King Zhending, son of the King Yuan of Zhou.

His grandson was King An of Zhou.
Gong Liu
Gong Liu or Duke Liu
(Chinese: , , "Gōng Liú") was a noble of ancient China.
He was an important early leader of the Ji clan, which later founded the Zhou dynasty.
His father was Ji Ju.
King Nan of Zhou
King Nan of Zhou (?–256 BC), born Ji Yan and less commonly known as King Yin of Zhou, was the 37th and last king of the Chinese Zhou dynasty, the son of King Shenjing of Zhou and grandson of King Xian of Zhou.
He was king for fifty-nine years, the longest in the Zhou Dynasty and all of pre-imperial China (in terms of the reign length followed by King Mu of Zhou).
By the time of King Nan's reign, the kings of Zhou had lost almost all political and military power, as even their remaining crown land was split into two states or factions, led by rival feudal lords: West Zhou, where the capital Wangcheng was located, and East Zhou, centred at Chengzhou and Kung.
Therefore, Nan lacked any personal territory and was effectively under the control of the local feudal lords, essentially relying on their charity.
However, Nan's symbolic and ritual power remains disputed.
On one side, the Chinese states largely ignored the king's activities and adopted royal titles and rituals for themselves, while the dynasty's fall generally received meagre contemporary coverage and attention.
This led to the assumption that Nan no longer had any symbolic power or semblance of royal authority left.
On the other side, recent epigraphic discoveries and some accounts in the Records of the Grand Historian and Zhan Guo Ce suggest that until his death, Nan was still respected as the Son of Heaven.
Either way, the last king of Zhou managed to preserve his weakened dynasty through diplomacy and conspiracies for fifty-nine years until his deposition by Qin and death in 256 BC.
King Xian of Zhou
King Xian of Zhou, or King Hsien of Chou, was the thirty- fifth king of the Chinese Zhou Dynasty and the twenty- third of Eastern Zhou.
Very little is known about him.
He succeeded his brother King Lie of Zhou in 368 BC.
He sent gifts to many of the feudal states, supposedly his vassals, particularly Qin and Chu. Late in his reign, the leaders of the states declared themselves kings, and ceased to recognise the king of Zhou as even nominally their overlord.
After his death, his son King Shenjing of Zhou ruled over China.
King An of Zhou
King An of Zhou was the thirty- third king of the Chinese Zhou Dynasty and the twenty first of Eastern Zhou.
He succeeded his father King Weilie of Zhou on the throne of China in 401 BC.
After he died, his son King Lie of Zhou ruled over China.
His other son was King Xian of Zhou.
King Si of Zhou
King Si of Zhou was the thirtieth king of the Chinese Zhou Dynasty and the eighteenth of Eastern Zhou.
He gained the throne in 441 by killing his older brother King Ai of Zhou, but was himself killed by his younger brother King Kao of Zhou after only five months of rule.
Ji Ju
Ju (Chinese:) was a noble of the Xia.
Born Ji Ju , he is reported as having abandoned the agriculture of his father Buzhu and grandfather Houji in favor of the animal husbandry practiced by the Rong and Di barbarians.
His son was Duke Liu, from whom the Zhou royal family descended.
Shu Yu of Tang
Shu Yu of Tang, surname( 姓): Ji( 姬) given name( 名): Yu( 虞), and Ziyu( 子於), was the founder of the State of Tang during the early Zhou Dynasty( 1046 – 771 BC) of ancient China.
The State of Tang would later be renamed Jin by Shu Yu's son and successor, Xie.
He was the son of King Wu of Zhou and the younger brother of King Cheng of Zhou.
Shortly after the establishment of the Zhou Dynasty, King Wu of Zhou died.
His son, Prince Song, ascended the throne and became King Cheng of Zhou.
Since he was very young and too inexperienced to run the newly founded dynasty, his uncle, the Duke of Zhou, served as regent and handled all political affairs until King Cheng of Zhou became old enough to rule.
In the year that King Cheng of Zhou ascended the throne, the people of a land called Tang( 唐) rebelled, so the Duke of Zhou conquered them.
According to the Records of the Grand Historian, one day, King Cheng of Zhou was playing with his younger brother, Prince Yu. King Cheng of Zhou suddenly picked up a parasol tree leaf and gave it to Prince Yu.
Then he said playfully," Let this be a proof that I will make you a feudal lord."
Prince
Yu happily got the leaf and he then told this to the Duke of Zhou.
The Duke of Zhou thought that whatever the young King Cheng of Zhou said should not be taken lightly since he was the king.
The Duke of Zhou approached the young king and asked him if it were true.
The young king said that he was just joking with his brother.
Then the Duke of Zhou replied," A sovereign must not joke about the things he says and do as what he has said."
The young king thought it was reasonable and gave the recent conquered called Tang land, west of modern Yicheng County in Shanxi, to his brother, Prince Yu. Shu Yu's son and successor, Xie, moved the capital Jiang( 绛) nearer to the Jin River and renamed the state Jin.
Jinci was a shrine in Taiyuan dedicated to Shu Yu.
It is a major historical and cultural site protected at the national level in People's republic of China.
King Shenjing of Zhou
King Shenjing of Zhou, or King Shenching of Chou, was the thirty- sixth king of the Chinese Zhou Dynasty and the twenty- fourth of Eastern Zhou.
His personal name was Dìng, whilst his ancestral name was Jī. He is commonly known as King Shenjing; this was actually his posthumous name.
It means" prudent and tranquil".
He was a son of his predecessor, King Xian of Zhou and thus nephew of King Lie; his paternal grandfather was King An of Zhou.
Shenjing fathered his successor, King Nan of Zhou, who had a very long reign.
