I was born in August 1979 (a sheep), but I changed my age when I was a child, and I have been a monkey for 80 years. What is my fortune telling?

Fortune telling is based on your real birthday time. The date when you became a monkey is the fate of the person who was really born at that time, and your fortune-telling must be your true information to become your numerology. Numerology is fixed at birth and cannot be changed just by changing the date casually.
