What problems can I solve besides fortune telling? What problems have actually been solved?

I think your question is a bit inappropriate.

Because the Book of Changes has not solved the so-called fortune-telling problem you said, fortune-telling with the Book of Changes is only the tip of the iceberg, and modern people only magnify this point. The Book of Changes is regarded as a leading figure in classical literature. Is it just a fortune-telling book? I can tell you responsibly that without the Book of Changes, China's ancient thoughts would be pale and rootless.

Of course, it is not impossible to use the Book of Changes to tell fortune, but the Legend of Coherence says: "A gentleman plays with his words when he is alive, and plays with his business when he is moving." It is "playing with his profession", that is, taking divination as a game and observing the changes of yin and yang through the process of divination.

As for your question, "What problem can you solve?" And "what problems have actually been solved?" I think we can answer together. I can still tell you responsibly that the Book of Changes has not solved any problems, and it has not solved any problems so far. After reading the Book of Changes, you can't get a promotion or a raise. It is "useless" learning.

However, the "useless" use is actually a "great use". When you really enter the "Yi Jie", you can feel the universe and understand life; Shaw lives a clean life. This is also the meaning of "harmony with heaven and earth, and ghosts and gods" in Cohesion Biography.

Don't be frightened by classical Chinese. When you really read, the words are actually redundant.
