Is the Buddha pigeon accurate in calculating eight characters, and is Chang accurate in calculating hexagrams?

I don't think anyone can be absolutely accurate, and often it is no exception. But Mr. Chang calculated it for me and told me everything in my family from several directions. He also told me my questions, my parents' health, my wife's work and what was around my grandfather's grave, all of which were quite accurate. Personally, I think Mr. Chang has real talent and practical learning. He is easy-going and speaks well in class. The charge is a bit high, but as long as you go to him, I believe he will make you feel worthwhile. That's what I thought.
