Why is Qin Shihuang's wife unknown?

This is because Qin Shihuang had no wife at all. There are very few records about concubines in Qin Shihuang's harem in ancient history books. It is impossible to know how many concubines there are in his harem and whether anyone is favored by him alone. As far as Qin Shihuang's wife is concerned, most scholars in later generations think that Qin Shihuang probably never had a wife. The reason why I think so is that there are no relevant records in ancient books, and the second is that the mausoleum of the queen has not been found in the Qinling Mountains.

In fact, judging from the number of children of Qin Shihuang, there should be many concubines in his harem. But none of these women can become the wife of Qin Shihuang, that is, the queen of Qin Dynasty, because Qin Shihuang felt that these women were not worthy of him. As we all know, the Qin Dynasty established by Qin Shihuang opened a new era, and Qin Shihuang also spoke highly of his achievements. Based on this self-knowledge, Qin Shihuang would not allow himself to find any woman as his wife, but he was too harsh on his post-marriage conditions, which also led to his never getting married.

In addition to this reason, another reason why Qin Shihuang did not attach importance to his wife was that he was too busy at work. Before the establishment of the Qin dynasty, Qin Shihuang was busy unifying the six countries; After the establishment of the Qin Dynasty, Qin Shihuang began to be busy unifying written and monetary affairs, striving to stabilize the rule of the Qin Dynasty at an early date. After the development and stability of the Qin dynasty, Qin Shihuang began to be busy seeking the law of immortality. Because of this busyness, the great events after the establishment were inadvertently forgotten by Qin Shihuang.

However, these reasons are only speculations of later generations. Why Qin Shihuang didn't stand up is now impossible to study. In fact, not only was Qin Shihuang never established, in fact, even the choice of a prince, which is related to the fundamental affairs of the country, was not established in advance. Qin Shihuang didn't make a will in a hurry until he was dying of illness, and let his eldest son return to Beijing to support the overall situation. But because the testamentary edict was done in a hurry, it provided an opportunity for Zhao Gao. In the end, Zhao Gao disobeyed the testament of Qin Shihuang and supported Hu Hai as emperor. Only a few years later, the Qin dynasty quickly went to ruin.
