What is history: it is the echo of the past to the future, the reflection of the future on the past. - Hugo
China's feudal dynasty has a history of thousands of years, and in this long history, many dynasties have emerged, of which the Tang Dynasty is a very prosperous feudal dynasty, when other countries will send Tang envoys to learn from the Tang Dynasty. In addition to being a relatively powerful dynasty in China, the Tang Dynasty also gave birth to China's first female emperor, Wu Zetian. However, when Wu Zetian abdicated in his later years, he returned the Jiangshan he had taken from Li Shi.
Wu Zetian

Wu Zetian entered the palace at the age of 14 and finally succeeded in becoming Li Shimin's concubine by virtue of his beauty. However, Wu Zetian is not a person who is willing to be in the harem, so she is also very concerned about politics and learns related knowledge. However, Wu Zetian's political methods were too vicious, so Li Shimin did not let her pay too much attention to the affairs of the DPRK. Later, after Li Zhi ascended the throne, Wu Zetian was reused and also adopted her as his concubine.
Li Zhi was very kind to Wu Zetian, and would let him go to the court together every day, and eventually let Wu Zetian have a basis for ruling the imperial court. Later, Li Zhi died, and Wu Zetian became the female emperor of the Tang Dynasty by means of poisonous means. However, in Wu Zetian's later years, she returned Jiangshan to the Li family, which made many people wonder.
Why did you return Jiangshan to the Li family?
In fact, when Wu Zetian was about to abdicate, she also thought about passing on her position to her own family, but there was no one in her family who was directly related to him, and the person who was most related to Wu Zetian was Li Xian. Moreover, there were many people in the dprk who supported Li Xian's ascension to the throne, and Wu Zetian discovered one thing when she was deliberating for a long time on who to choose to inherit the throne.
Almost all the ministers were very supportive of Li Xian, and the more important people also had great calls for Li Xian's ascension to the throne. So at this time, Wu Zetian understood that sitting on the throne was actually not what people wanted to see. And during her reign, she did not reverse the position of the Li clan in people's hearts, so she chose to return Jiangshan to the Li clan after abdication.
