If Zhouyi is really so magical, why is China so modern?

First of all, it played a decisive role in ancient times only in the Oracle Bone Inscriptions era of Shang Dynasty. At that time, everything had to be divined. In the Zhou dynasty, patriarchal clan system was emphasized and Zhouyi was not taken seriously. Basically, it has only become academic research, not to mention the pragmatism of the Warring States period. After the unification of Qin Dynasty, books were burned to bury Confucianism, including Zhouyi. Therefore, there is no need to drag the reasons for China's backwardness in modern times into Zhouyi. In fact, the ancient culture is modern.
