The best feng shui is your kindness, sympathy, gratitude and filial piety. Different people live in the same house and have different fates. If you rely on those guys who cheat people with Feng Shui, you can only be useless or attract demons.
Looking at feng shui, fortune telling is a vulgar thing, and decent people simply despise dealing with such people, let alone entering the industry.
The real Feng Shui book is called Yang Gongfeng Shui, but he is a eunuch in the Tang Dynasty and has no descendants. His nephew has an heir, but most of them are overseas.
So there is no real person.
