in response to the initial post, if you are talking about wind and fire being part of the 5-phases (fire, earth, metal, water, wood) then the wind aspect relates to wood. Qi is energy and the 5-phase theory breaks down the changes in this energy and isnt related to just one of them. if the energy is at it's peak then it is related to fire, metal-descending, earth-stable, water-nadir, wood-ascending. have a read of the i-ching and the yellow emperors classic of medicine-"suwen" to gain a clearer understanding on this.

hope it helps
