How many people in Zhongshan are reading the Book of Changes?

I'm watching it myself. Some people regard the Book of Changes as a symbol of feudal superstition, but mainland media rarely report it because of its many policies. In fact, there is still a lot of research on it. Unveiling its divination is actually a rather profound philosophical book. However, it is said that I won't read the Book of Changes until I am forty years old, and I also want to ask an expert to give me some advice.
