Is Master Moya A a Real Feng Shui Master?

I have read Teacher Mo's Four-Pillar View of the Sky, which is very good, much better than any of his books, clearly adjusted and easy to learn and understand. In particular, it is only necessary to judge the five elements to produce grams, which is completely in line with the principle of the Book of Changes. However, due to work problems, I haven't taken part in the study, so I must go to Bai Mo as my teacher in the future!
