Most Feng Shui Masters that you come across would advertise themselves claiming to be consultants for reputed VIPs, politicians, and celebrities. Rest assured that the luck and destiny of such high-profile people would be markedly better. As a result, even an average feng shui master might appear better than he might be, by riding on the good luck of such high-profile people.
Appearing regularly on television programs
It would be in your best interest to avoid the ones appearing regularly on television programs; as such programs have been usually sponsored by these practitioners. Moreover, the cost of sponsorship could be prohibitive. You might have a decent idea about the end customer paying for such prohibitive sponsorship costs.
Overly commercialized masters
If you come across an overly commercialized Feng Shui master, rest assured that they would have little time to upgrade their knowledge. As a result, they might not be relevant in their practice. Therefore, it would be in your best interest to choose a Feng Shui master who knows how to teach Chinese Metaphysics, as it would be the best way for them to stay updated with the modern world. It would also enable them to customize their Feng Shui methods accordingly.
Having focus on fame and profit
Moreover, an overly commercialized practitioner would focus on fame and profit that they might be doubtful in the process. While most would claim to have adequate understanding and knowledge of Zi Wei Dou Shu or ZWDS, they would outsource the reading of Zi Wei Dou Shu to the other firm. In case, you approach them personally to discuss Zi Wei Dou Shu, they might find excuses and avoid entertaining you. They might also not provide you with free advice, as they require you to pay so that they could pay the firm further whom they contracted for reading ZWDS assignments.
Subcontracting authoring of books
Yet another trick of a highly commercialized Feng Shui master would be to subcontract the authoring of books, especially the Annual Horoscope books. It would enable them to enhance their visibility while they could not be bothered to write. It would be surprising that the contents of such books have been circulated or shared at times among various practitioners having an alliance.
You might come across a few instances where you could find similarities between a few such books. Regardless of the case, these books have been usually ineffective, as using twelve zodiac animals to speak about the luck of people on seven continents would be none other than general talk.
