There is a classmate's husband surnamed Cai, very small, but very shrewd, she always calls it "small dishes", very accurate and image. There is also a female classmate, whether it is a teacher or a classmate, all call her Xiao Cai, and she feels a super sense of correspondence. You may have also seen people with the surname Cai, maybe the characteristics are not strong, so there is no memory, and the impression of people with the surname Cai looks like a small person.
I want to know what genes cause the people of the old Cai family to be so short and concise, after studying, I learned that in fact, the Cai surname and many surnames are derived from the Ji surname, and the ancestor is one of the three prisons in the famous historical story "Three Prisons Rebellion", "Prison" is the official who supervises the remnants of the former dynasty. From the story, I feel that he has some suspicions of lifting a stone to drop his own feet, shrewd but being shrewd and mistaken-
Cai Shudu , formerly known as Ji Du , was the fifth son of Ji Chang the King of Zhou wen and the younger brother of King Wu. After King Wu destroyed the Shang, he gave him the area around Shangcai in present-day Henan and established the State of Cai, which was later called Cai Shudu. If ordinary people can be a prince, they are also old and beautiful, but this guy still wants to continue to ascend to the throne, and even after the death of King Wu of Zhou, he took advantage of the young age of The Succeeding King Cheng, Ji Shu, to join forces with the other second prisons to rebel, and they knew that Zhou Gongdan, who was the regent of the Dynasty, was the real wise man and perfectly quelled the rebellion. Three and two died one by one, and it was Cai Shudu who was expelled, and he died depressed without going far.
Later, Zhou Gongdan found that Cai Shudu's son Hu was good, had both moral integrity and ability, and was stronger than his father, so Zhou Gong suggested that King Cheng reseal Hu Yu Cai and rebuild the state of Cai, known in history as Cai Zhong, hu really lived up to the expectations of the people, always abided by the moral precepts of King Wen, and achieved outstanding political achievements. The Cai kingdom hereditary 25 kings spent nearly six hundred years before being wiped out by King Hui of Chu. The people did not forget their own country, so they took Cai as their clan. Although Cai Shudu is not considered, he is after all Cai Zhong's father and the founder of Cai Guo, so he is still a veritable ancestor of the Cai surname!
