As a master of Feng Shui, Yuan Tiangang didn't give Wu Zetian divination.

First of all, he was afraid that Wu Zetian would kill him. He is a master of divination, and divination is generally accurate, so many people want him to do it for them. However, he had already decided that Wu Zetian would become an emperor in the future, but in this case, he dared not talk nonsense, because he was afraid that it would lead to fatal disaster, saying it was an open-air machine. Later, Wu Zetian really became an emperor. It can be said that the whole world belongs to Wu Zetian. No one dares to disobey her. If he is asked to do divination, he will definitely work out the fate of Wu Zetian. He dared not talk nonsense, fearing that Wu Zetian would kill him if something happened. Because after all, it is not easy for Wu Zetian to ascend to the throne alone, because she is ruthless and can kill her own daughter and son, not to mention that she is a fortune teller.

Secondly, he didn't want to reveal the secret. People who do divination have their own unique skills. They generally don't like to tell others what they have worked out, unless they are charlatans who make money from it. They must tell others the results of their calculations. And the Wu Zetian he faces, if he doesn't tell Wu Zetian then, will definitely be killed. So he thinks we should solve this matter from the root, that is, don't calculate her.

In the end, I never gave her divination, so that Wu Zetian had a feeling that he still had use value, so that she would not kill him easily. It can be said that everyone in the palace was struggling for survival at that time, and he was no exception. He chose not to predict Wu Zetian in order to save his life. Emperors generally connive at people who will be of use again and again, and so does Wu Zetian. So he will give Wu Zetian the illusion that he still has use value. .......................

In a word, he didn't plan Wu Zetian because he didn't want to die.
