Back to Qin and three years, no children. Why did he and Ed have two children?

According to historical records, at least three men had sexual relations with Evonne, one was Lv Buwei, the other was Wang Xiang in Qinzhuang, and the other was Ai. When Qin Shihuang ascended the throne 13 years old. How many children did Evonne give to Zi Chu? The existing history books are not recorded in detail. The only certainty is that he gave birth to Ying Zheng. Therefore, it cannot be said that Evonne was not pregnant after Zi Chu ascended the throne, and he can only look forward to future archaeological discoveries. As for the affair between Evonne and Lv Buwei, why did Evonne give birth to Ai's child instead of Lv Buwei's?

Let's talk about fertility first. There is a saying in Huangdi Neijing that men arrive in 28 days, women arrive in 27 days, and then men and women have children. So people at that time already knew that men and women could have children after sexual maturity, and it was not too late. It can be seen that the ancients also understood that there was a safety period, but it was not as accurate as it is now. In the same way, there were corresponding contraceptive methods in ancient times, but I don't know what contraceptive methods were available in the pre-Qin period for the time being.

Let's talk about the birth situation under normal circumstances. According to the current research, if the average age is 20 years old and sexual life is not interrupted until the end of childbearing age, each person will have about 7.5 children on average. If the age of first marriage is postponed to 26, other things being equal, the average number of children will be only 70% of the former, about 5.5.

Lv Buwei is a smart man, knowing that keeping this underground relationship with Evonne for a long time will lead to great things, so he went to Ai. Since Lv Buwei is so clever, how can he leave the children behind? Therefore, although Lv Buwei and Zhao Ji have a "special relationship", they still insist on the bottom line of not letting Zhao Ji have children.

Ai is different. He is the successor that Lv Buwei found for him. If he doesn't "work hard", he will probably be pushed down, and he will probably be silenced in order to keep a secret. So, LaoYi tried to "please" Evonne, so of course, a child would be born, and with the child, Evonne would be more at his mercy.

Mrs. Liu Bangzhi was very fond of her, and both of them had only one son, Ruyi Zhao. Obviously, the pregnancy rate at that time was not very high. Therefore, Lv Buwei's self-restraint, coupled with objective reasons, makes it normal for Evonne not to have children. In order to survive, prosper and go further, Lao Ai certainly had to please Evonne. Having children with Zhao Ji consolidated his position and made Evonne love him more. Then he wants to exchange his children for more power capital.

It's a pity that he met Qin Shihuang, who is hard to get out in a thousand years, and helped shake the tree. Of course, he ruined his future. Therefore, after Zi Chu's death, whether Lv Buwei and Evonne had no children or Evonne had two children in Laoai was the result of their own initiative and objectivity.
