What if twins appeared in the history of the ancient eldest son inheritance system?

Ancient emperors gave birth to twins. I have only seen one case, that is, Yiwu, Gong Hui, the State of Jin in the Spring and Autumn Period.

Kim is a son, a brother and a former monarch.

Due to the disaster of the motherland, Jin Wengong Zhong Er was exiled 19 years. Yi Wu had a similar experience, but not for that long. He ascended the throne with the support of Qin, but in turn disrespected Qin, and finally angered him (this was also the Lord who was not to be taunted in the Spring and Autumn Period. Five tyrants? 1) He sent troops to attack Jin and directly captured Jin.

This is the soft power of Jin State. Although there were contradictions between the monarch and the minister, when the disaster came, the ministers held on? You humiliated me to death? The principle of unity, did anyone voluntarily follow the captured Jin to Qin? Non-violent and non-cooperative peaceful demonstration; Some stay at home, govern the country, save food, train military forces, and wait for the monarch to return home; Qin Mugong, the elder sister of the State of Jin, sent a letter to her husband. You are the monarch, and so is my brother. The two monarchs should not meet under such circumstances. If you treat my brother as a prisoner and take him to Beijing in the morning, I will take my children to set myself on fire at night, and I will take my children to Beijing the next morning? .

Under pressure, he treated Kim with the courtesy of the monarch and sent him back to China after a period of detention. ? Of course, unconditional release is impossible.

Okay, let's get back to the point. This gold gave birth to twins, and they are twins. The fortune teller said it was bad for the child's life, so Kim named his son? Hey? , the meaning of slaves; Name your daughter? Concubine? , not a little wife, but also a slave.

Although they are twins, they are not fighting for the throne because of a man and a woman. When Jin returned to China, his son stayed in Qin as a hostage. Later, after his death, he fled back to China and succeeded to the throne. But soon, his uncle Zhong Er returned to the State of Jin with the help of the State of Qin and seized the throne. From then on, the state of Jin, the whole history of the Spring and Autumn Period, began the era of Jin Wengong.

In the history of China, the eldest son is a twin. I only know this case.

But then again, twins are not born together. Even if there is a gap of five minutes, you can see the difference between a young brother and an old brother. Therefore, in the eldest son inheritance system, there is no need to worry about twins.
