Chinese system of environmental energies (4,4)
I believe the answer is:
feng shui
'chinese system of environmental energies' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for feng shui that I've seen before include "Chinese principles of the flow of energy in buildings" , "Chinese system of environmental energies" , "Chinese values" , "Chinese tradition" , "Chinese furniture arranging to produce happiness" .)
