Why is Zhu Yuanzhang superstitious about fortune telling?

Why is Zhu Yuanzhang so superstitious about immortals?

In fact, every founding emperor was superstitious about God, not because he believed it himself, but because he wanted others to believe it. Because they are not orthodox people themselves, they are usurpers. The only way to make people obey them is to make them believe that they represent providence, and there is a very strong backer, which is providence.

Zhu Yuanzhang, he is a practical man. He made every step on his own, and never had any opportunism. So he believes that the gods are not in his own belief, and he is not the kind of belief that leaps over the earth. He is constantly struggling, trying hard, and at the same time promoting himself, that is, he represents God's will to destroy other armies and also saves the local people with God's will. That's why he was as successful as bamboo in his later years.

His so-called belief in the gods is not ordinary. He wants to worship Buddha, go home and sleep, so that he can be emperor. I think he is the only recognized Buddha in heaven, and he is himself. He is super confident in himself.
