It is said that the so-called "feudalism" began in the Western Zhou Dynasty. After the Zhou Dynasty eliminated the Yin Shang, for the sake of the stability of the country, they divided their surnames in different places, trying to use blood relatives as a contact to reduce the scourge of killing with different surnames.

The number of the same brothers of King Wu of Zhou, according to Taishi Gong, was a total of ten. After King Wu took over the world, these close relatives were of course his priority objects. Among these ten people, there is a person named Zhenduo, because he is the younger brother of King Wu, and everyone respectfully calls him "Shu Zhenduo". This Zhenduo was sealed in "Cao", and under his rule, it was the "Cao State" from the Western Zhou Dynasty to the Spring and Autumn Period and the Warring States Period.

From Cao Shu Ji Zhenduo to Ji Boyang, there were a total of 26 supreme rulers, which lasted for 636 years. During the 636 years, these supreme rulers, who were able to follow the laws passed down from father to son, were basically able to die well; Anything that cannot be inherited according to the law is basically seized by bloody slaughter, and the power obtained in this way rarely has a good ending, you don't follow the rules, others can not follow the principles, you can kill others, others can also cut off your head. This shows both the bloody side of the power struggle and the importance of mutual observance of agreements. History will not repeat itself, but history will be similar. During the French Revolution, those who sent others to the guillotine were later killed on the guillotine by the same means. If those in power use their power to create chaos, once they lose power, this chaos will mostly reappear in him. We may not see the future, but if we can find some relief in the "present world newspaper" of history, it can be regarded as a ray of light to guide forward.

Cao was a small country, and in the environment of great power competition for hegemony at that time, what was needed to survive was judgment. If a balance can be found between the great powers, the danger of extinction will be much less. If you are not careful, you are on the wrong side of the line, and you may overturn overnight. This is the difficulty of small countries. The survival of a large country depends on strength, and the survival of a small country depends on wisdom. This was useful and practical in an era when there was still some emphasis on etiquette.

At the end of the Cao Kingdom, the political chaos can be imagined. Why? The last five supreme rulers of the Cao state, one was captured and died in the Song state; The two were "killed" - that is, they were killed in the conflict between the following crimes, in fact, these two murderers also became the killed ones in the end; A lord of the dead country, who was killed in the Song Kingdom in a foreign land. If you want to destroy it, you must first let him mess up. This was true thousands of years ago, and it will be true a few days later. Not to mention the far-reaching, none of the regimes that have fallen in the last decade or two did not start with internal chaos. There may be no scientific laws to calculate history, but the significance of history is still worth pondering. The death of one supreme ruler after another is a warning sign for the state, and the internal order of the Cao State can be imagined.

Ji Boyang's father, Cao Jinggong, was lucky to die after killing the previous leader and sitting on the throne for four years. Cao Jinggong's death, there was no abnormal situation, and he passed the throne to his son Ji Boyang as a matter of course. It is guessed that after so many political treacherous changes, the situation in Cao Guo at this time is already a decadent scene.

In the third year of Ji Boyang's reign (499 BC), a person in the Cao State (hereinafter referred to as "Cao Guoren") had a dream. "Cao Guoren" dreamed that the supreme rulers of the countries gathered together in front of the palace where Cao Guo placed their ancestors, and they planned together to destroy the temple and shrine of Cao State. At this time, the founder of the Cao State, Cao Shu Zhenduo, the younger brother of King Wu Ji Fa, appeared, and he tried to stop the gang from exterminating Cao. Cao Shu Zhenduo said to these people:

"Can you wait for Gongsun Yi (Qiang), and when he comes, it's not too late for you to implement the plan."

The supreme rulers of the countries, speaking of it, most of them can still get close to Cao Shu Zhenduo to some extent, and thinking that everyone was once a direct descendant of King Wu, they gave Cao Shu Zhenduo enough face and promised to wait for Gongsun Yi to come before doing it.

After dawn, "Cao Guoren" felt that this dream was a little strange, so he asked around to see if there was a person named Gongsun Yi in Cao Guo. However, he asked almost all the places he could know about Cao Guo, but he didn't find the number one person Gongsun Yi. "Cao Guoren" was a little annoyed, he did a careful study and analysis of his dream, and then said to his son:

"Son, if one day my father dies, I will not be able to take care of you. After my death, if there is a powerful faction named Gongsun Yi in charge of the government in Cao State, you should quickly pack up and leave Cao State as soon as possible to make a living elsewhere, so as not to encounter trouble. ”

Ji Boyang is a person who likes to hunt very much. In the sixth year of Boyang (496 years before the park), Ji Boyang met a man while hunting, this man was a farmer, his name was Gongsun Yi, and he also liked to shoot hunting. On that day, Gongsun Yi happened to meet Ji Boyang, who was also hunting, and he dedicated the white goose he shot down to Ji Boyang. Two like-minded people hit it off at first sight, so the two of them talked about hunting on the way. Ji Boyang felt that he had met a talent and was very happy, so he summoned Gongsun Yi to the imperial court and entrusted him with full authority for state affairs.

The son of the "Cao Guoren" fled from the Cao State after hearing that Gongsun Yi was in power, and the next thing was that Ji Boyang was abducted to the Song State, dumped his body in a foreign land, and the Cao State perished.

The dream of "Cao Guoren" is very insightful. Sometimes, the masters are in the folk. The stupidity of those in power when they get carried away by power is incredible.

The dream of "Cao Guoren" is a visionary dream!
