What is fortune telling? Is there really a destiny in life?

I don't know what fortune telling is, but life really has a destiny, and I was skeptical before. I once saw a saying that those who believe in fate follow good luck, and those who don't believe in fate are led by fate. I saw this sentence in the Feng Shui exchange forum where cats learn to learn, so I looked for the cat's door, which subverted my understanding of fate, because they broke many things in my past, including now, through the principle of five elements.
