What was Yuan Tiangang like in history after the death of Yuan Tiangang, the "demon generation"?

Yuan Tiangang was a famous astronomer, astrologer and forecaster in the Tang Dynasty. In today's words, he will be a fortune teller, but Yuan Tiangang's fortune-telling is so accurate that he even predicts the future. Yuan Tiangang was also called a brain trust by Emperor Taizong. In 634, Yuan Tiangang died suddenly at the age of 72. After Yuan Tiangang's death, the prediction of his date of birth came true one by one, which is amazing.

Yuan Tiangang is most famous for her prediction of Wu Zetian.

According to records in the Tang Dynasty, when Wu Zetian was just born, Yuan Tiangang went to Wu Zetian's house to congratulate her. When Yuan Tiangang saw Wu Zetian's mother, she said with surprise, Your wife is going to have a baby. So Wu Zetian's mother first took her two sons out to visit fortune-teller Yuan Tiangang. Yuan Tiangang just shook his head and said it wasn't them. Then Wu Zetian's sister was brought out. As soon as Yuan Tiangang saw that he hadn't arrived, he asked, Does your wife have a son? Wu Zetian's mother saw that Wu Zetian was still in infancy, and Wu Zetian was wearing men's clothes. Yuan Tiangang mistakenly thought it was a boy, but unfortunately said: If it's a girl, you can't spy, and then you should be the master of the world.

History has proved that Yuan Tiangang's speculation is correct. In the first year of providence (690), Wu Zetian proclaimed herself emperor and became the first female emperor in the history of China.

As mentioned earlier, Yuan Tiangang was called a brain trust by Emperor Taizong. One day, Emperor Taizong was idle and summoned Yuan Tiangang. Emperor Taizong wanted to test Yuan Tiangang and casually said: How long can the kingdom of the Tang Dynasty last? Emperor Taizong gave Yuan Tiangang a difficult problem, but if he didn't answer this question well, he would be beheaded.

Yuan Tiangang thought for a moment and replied: When Zhu Neng climbed the tree. Emperor Taizong laughed after hearing this. How can pigs climb trees? Emperor Taizong thought that Yuan Tiangang meant that the mountains and rivers in the Tang Dynasty could be strong forever, so he was happy to reward Yuan Tiangang. But Emperor Taizong forgot that Yuan Tiangang was a forecaster, but Yuan Tiangang could not reveal the secret, and Emperor Taizong did not understand the meaning of Yuan Tiangang's words.

God bless four years (907), Zhu Wen forced Tang Aidi Lizhu to meditate, claiming to be the emperor, establishing the Liang Dynasty and changing the Yuan Dynasty to Kaiping.

And then what? Zhu? Same? Pigs? Yuan Tiangang had long predicted that the Tang Dynasty would be destroyed by Zhu Wen.

There are countless magical legends about Yuan Tiangang, but the title is Yuan Tiangang? A generation of demon people? It's really inappropriate.
