I have tried to DIY Feng Shui, but the books give contradictory information

There was an explosive growth in the number of Feng Shui books. At the start of the 1990s, there were less than a dozen books on this subject. In 1997, 54 titles were published, 1998, 73 titles were published, 1999 (Jan to Apr) 40. (Ref: Feng shui makes publishers feel good (Apr 1999)

Authors were under pressure to get the relevant information of a Chinese subject to get their books published. To justify authorship, they had to produce original material. 

I have read a number of these books and found the “core information” is based on these sourcebooks.  

• Feng Shui: The Chinese Art of Placement by Sarah Rossbach;
• Applied Pa-Kua and Lo Shu Feng Shui by Lillian Too;
• Feng Shui: The Ancient Wisdom of Harmonious Living in Modern Times by Eva Wong.

Also, the writers had to put their own spin on the matter to show originality and marketability to the publisher.

Secondly, authors have been adding procedures from other cultures into their books and using the term feng Shui. For example, Balinese Space Clearing, North American spiritual chants, Japanese Shinto rituals, western dowsing etc. This practice has added to the confusion to the knowledge core of Feng Shui, which is of a Chinese Origins.

In my opinion, this is the cause of contradictory information of this generation of books.
