Princess Wu Zetian????? She has never been a princess, only a concubine, empress consort, empress dowager , and empress regnant!!

you guys know little about Chinese history and Chinese ancient cultural tradition.
If an emperor died,his wife had no right to come into power.
Order of Succession :his son,his brother,his nephew on his brother's side,his cousin on his father's side,a son of his cousin.
As for her so-called cruel murder,nobody knows whether
or not it was a truth.those historians dislike her just for her sex.They can manufactured something to fool people.The similar case happened on Cao cao,who had been insulted by ancient scholars for his origin.
Too many rumors.
