What does the fortune teller mean when he says I have hidden diseases? Please kindly help explain, thank you very much!

Eight defeats is a hidden disease. It just means that the month when you were born is not good. Let me show you, plus heavenly stems and earthly branches's Yin and Yang elements. In the month, you may not be able to do anything with your parents, and you may have external diseases. It is unscientific to only look at the time of year, month and day and tell fortune. I hope I can help you.
