Is Zhouyi pseudoscience? The essence of religion?

In some places, yes. First of all, Zhouyi is quite superstitious. And all the fortune-telling of Zhouyi are inaccurate lies, without any scientific basis. But one thing is good, such as gossip, which is directly related to Zhouyi. Without the emergence of Zhouyi theory, they could not develop well, which is conducive to the better spread of science and religion from this perspective. But as for fortune telling, it is nonsense, which seriously violates scientific truth and religious essence.
