On the talk page there is the following question:
Is this for real?
I can't find any references to this supposed system anywhere outside of Wikipedia. A google search for 火黑暗 reveals nothing to do with architecture, aesthetics, or feng shui. Of the sources given on this page I can't find the Von Erdberg (1936) online, but I did find a preview of Cai (2004) on Google Books, and searching this book for "火黑暗", "huoeheian", "fire and darkness" gives nothing either. The Chinese language wikipedia does not have an article on this subject either. Does anyone have any more info on where this concept comes from? --126.96.36.199 (talk) 00:56, 31 January 2018 (UTC)
There's no response.
This seems to be Field's translation, supposedly it was revised July 26, 2009, I'm not sure if anything got changed or not, but there seems to be nothing akin to the Wikipeida quote.
