Which minister in the Tang Dynasty can predict the future?

Li was a minister in the Tang Dynasty, and Yuan Tiangang was not an official in the current dynasty, so he could not be called a minister, but both of them could predict the future. Of course, this is the legend of our descendants, and it is also broadcast on TV. We know that these two people went on TV because when they were emperors, they predicted that a woman named Wu would take Li Jiashan's position in the future. Historians believe that these are all reasonable excuses that Wu Zetian gave herself when she was emperor.
