I believe that friends who have watched "Fengshen Yanyi" have a deep impression on Jiang Ziya. This is a character with great ability, and he is also good at socializing, and all kinds of immortals have to sell his face.
We all know that his surname is Jiang, the name Shang, the word Ziya, so it is also called Jiang Shang.
However, when we open the history books, we find that there is more recorded on them, and it is a person named "Lu Shang".
For example, in the "Chronicle of History", it is recorded in many places:
"King Wen of the Former Zhou Dynasty thought that Lü Shang was too duke." "In the past, Lü Shangzhi met King Wenye, and as a fisherman, he fished in Weibin'er." ……
It is reasonable to say that King Wen of Zhou was on the edge of the Weishui River, and did not he encounter Jiang Shang? How did it become Lu Shang again?
Are these two names the same person?
In fact, Lu Shang and Jiang Shang are the same person, referring to Jiang Ziya.
It's just that Jiang is his surname and Lu is his surname.
Next, the question arises: What is the difference between surname and surname? Can it be mixed?
Before the Qin and Han Dynasties, the difference between surname and surname was still very large. Among them, the surname is handed down from the ancestor and basically will not be changed, while the clan will be different according to the difference in official position and fiefdom.
This is what the ancients said:
"Those whose surnames are subordinate to the places of their ancestors, and those whose clans are divided by their descendants."
As for Jiang Ziya, why can it be called Jiang Shang, or Lu Shang?
This is because his ancestor Boyi, who assisted Emperor Shun with meritorious service, was made a marquis and had a fief in the state of Lü, so he had the Boyi Lü clan, which was not the same person as Boyi who later "did not eat Zhou".
And calling Jiang Shang Lü Shang means Jiang Shang of the Lü Kingdom.
Of course, this was before Qin Han. During the Qin and Han dynasties, surnames and surnames became one, and many people began to "take the surname as a surname".
In fact, this phenomenon existed during the Spring and Autumn Period and the Warring States Period.
Take Confucius, for example. His father's surname was Zi, the name Qi, the character Uncle Liang, and later generations called him Uncle Liang Qi. Their family was originally a descendant of the King of the State of Song, and later ran to the State of Lu with the family, and was named the Grand Master of The State of Lu, and "Kong" was his clan.
Later, his father's uncle Liang Qi used his own surname as confucius's surname to let him open another family.
Why? This is because people at the time believed:
"The fifth generation is close to the end, don't be a public family."
That is to say, after five generations, the blood relatives have been exhausted, and they can go to the branches and leaves again. This is also the reason for the old saying, "Gentleman's Zee, the fifth and the cut".
Of course, the ancients did this, and there is a more important layer of consideration.
Close relatives do not marry, this truth, the ancients understood very early. But how to define, is it a close relative?
The first stipulation of the ancients was "marriage without the same surname".
Unfortunately, the ancestors are so many, and there are so many surnames handed down, and the scope of activities of the ancients is not like now, and the heavens and the sea and the north want to go. In this way, there are obviously fewer and fewer people who can be married.
In addition, from the perspective of blood and kinship, after five generations, it is actually exhausted and can be married.
What to do? It's about creating more surnames.
This is the origin of the hundred family names.
