When Wu Zetian was still very young, she was already taken by Li Shimin, because she was originally a very talented girl, and because she could be seen by others, she had to aspire to become an excellent person.
Later, because the age difference between the two of them was quite big, when Li Shimin died, Wu Zetian was still in his youth. So when Li Shimin died, did she have no backer?
Not really. Later, Wu Zetian was able to follow Li Zhi, which shows that Wu Zetian still had a certain kind of secret relationship with him at that time.
Li Zhi took her back to the palace and canonized her as a concubine, but she was not satisfied with this, she also wanted to become a bigger one, that is, to be able to be a queen. Because she has always been talented and ambitious, she has been learning about some of the regulatory aspects of the regime.
Then the reason why she became a female emperor later can be easily seen. Later, she would often take care of the affairs of the regime during the day, and at night, she also needed to rest, but she usually went to one place, which was the secret room in her dormitory.
Although in ancient times, it was not surprising that high-ranking people built one or two private secret rooms.
But what interests everyone is that Wu Zetian has to stay there for a long time every night, and when she comes out, she is covered with tears. So everyone is curious, what will she say in it?
In addition, the craftsman who repaired her secret room before is gone. So everyone was even more curious about what was inside, and later someone found that there were actually three portraits in it during archaeology, namely the portraits of Buddha, Li Shimin and Li Zhi.
Everyone should understand this, and they all know that Wu Zetian must be complaining to them inside. It turns out that such a powerful female emperor also has her own fragile side, so "why are there tears in her eyes" gradually spread.
