Someone asked, how many secrets are there in this world? I think no one can answer this question. Secrets have been with us throughout history, ever since the first seeds of thought were sown. But, as valuable as the secret itself is, a secret that is absolutely unknown is meaningless. Someone told me my fortune and told me what kind of living situation I would be in at some time in the future. The fortune teller had no clue. I was just the listener and felt the truth behind it. It seemed that I gave this unscientific judgment a mysterious color and deified it.
