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.
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.

Duke Ding of Qi (reigned c. 10th century BC) was the second recorded ruler of the ancient Chinese state of Qi during the Western Zhou Dynasty.

Duke Ding supposedly served King Kang of Zhou along with other major vassal state rulers including Xiong Yi, viscount of Chu, Count Kang of Wey (衞康伯), Xie, Marquis of Jin and Boqin, Duke of Lu.
However, most modern historians believe Duke Ding was in fact the fifth-generation descendant of Duke Tai, and he could not have served King Kang of Zhou.
After Duke Ding died, he was succeeded by his son Duke Yǐ of Qi.
