How to locate a "master"?

In Feng Shui, there are only academic arguments, and non-professionals say "nonsense". There are many ancient books and examples of Feng Shui, some of which are unpredictable, and Feng Shui can't have an accident soon, it should be far away! Fortune-telling also has ancient books! There are not many examples of naming ancient books, which is enough to prove practical and urgent. Nowadays, there are many business titles. No matter how good fortune-telling is or how smelly it is, it may not come true and die. The name is good, there are no dead people, so who can predict what to do?
