Why did Wei Zifu finally hang himself?

Because she tried to conspire with the prince, if she didn't commit suicide, I'm afraid the outcome would be even worse.

Wei Zifu became a queen from a singer, which can be said to be the favorite of the emperor. She didn't have a strong matriarchal family, so she was in awe of Emperor Wu at first. However, when Wei Qing and Huo Qubing were both important, and her son was made a prince, she began to swell.

Especially when Emperor Wu of the Han Dynasty began to guard against the prince and was dissatisfied with their mother and son, she went crazy. She didn't seek personal gain, didn't want to restore the king's trust, but wanted to overthrow the king and put her son on the throne. Of course, all this also has the inside story that Emperor Wu favored Taoist priests and alienated the prince.

But she shouldn't, shouldn't launch a rebellion, and shouldn't let the people suffer accidents. What she should not do is that in the society at that time, the harem was in charge of politics and supported her son to commit heinous crimes. What she should not do more is to educate an irresponsible prince, attempt to rebel, abandon people and flee, and let countless people suffer for him.

So she killed herself. First, she was accused of treason, and she was sentenced to death. Second, she may also want to use her own death to arouse the sadness of Emperor Wu of the Han Dynasty and let her son live.

It can be said that Wei Zifu is my least favorite queen. No, she is not qualified to be queen at all.
