Struggling to Teach ChatGPT Liu Yao Prediction—Need Guidance!

I tried to teach ChatGPT a prediction science, which is an ancient Chinese prediction science called Liu Yao. However, no matter how I talked to him, I tried many different ways of talking to him, but he couldn’t even accurately rehearse the hexagrams I gave him, nor could he remember the knowledge and hexagram interpretation logic I taught him. How can I make him understand what I say and train him to learn this skill according to my needs? Can anyone explain it to me? Thank you!
